libf2c/ChangeLog

   1 Sat Jun 13 03:46:40 1998  Craig Burley  <burley@gnu.org>
   2
   3         * Makefile.in (install): Don't install if $(libsubdir)
   4         is empty; issue a diagnostic saying top-level Makefile
   5         must pass it in instead, and exit.
   6
   7         * Makefile.in (g2c.h): Rename from f2c.h.
   8
   9         * Makefile.in, libF77/Makefile.in, libI77/Makefile.in,
  10         libU77/Makefile.in: Rewrite config and var assignment
  11         sections to be even more minimal than before, and to
  12         more clearly documented what macros are expected to be
  13         set and to what sorts of values.  Eliminate CROSS and
  14         related stuff, since there's no such things as CROSS
  15         in egcs.  Rename GCC_FOR_TARGET to CC throughout.
  16         * Makefile.in (stamp-libi77, stamp-libf77, stamp-libu77):
  17         Eliminate CROSS.
  18         * configure.in: Eliminate CROSS.
  19
  20         Rename libf2c.a and f2c.h to libg2c.a and g2c.h,
  21         normalize and simplify g77/libg2c build process:
  22         * Makefile.in: Remove all stuff pertaining to
  23         installation, cleaning, and so on.  Parent Makefile
  24         does all that now.  Pass F2C_H_DIR,
  25         G2C_H_DIR, and GCC_H_DIR, the pathnames for the
  26         directories containing f2c.h, g2c.h, and other
  27         #include files, to subdirectory Makefiles.
  28         (stamp-libf77, stamp-libi77, stamp-libu77):
  29         Don't specify `-f Makefile' anymore, it's not needed
  30         now that subdirectory makefile's from netlib are
  31         renamed to makefile.netlib in g77 source (and to
  32         makefile.ori by configuration process, in case they're
  33         still around somehow).
  34         (stamp-libe77): Don't make libE77 dir unless it doesn't
  35         exist, if it does just delete all objects in it.
  36         Compile using $(GCC_FOR_TARGET), not $(CC).
  37         (rebuilt): Remove this and all subordinate targets,
  38         as parent Makefile now handles all that.
  39         (*clean): Remove.
  40         * configure.in (Pad_UDread, ALWAYS_FLUSH, WANT_LEAD_0):
  41         Remove these and commentary to new f2c.h file.
  42         AC_OUTPUT g2c.h instead of f2c.h.  Remove old commentary
  43         regarding concatenation.
  44         * g2c.h.in: Rename from f2c.h.in, add appropriate
  45         commentary.
  46         * f2c.h: New file, a wrapper for g2c.h that does
  47         libg2c-specific stuff.
  48         * libF77/Makefile.in, libI77/Makefile.in, libU77/Makefile.in:
  49         Change $(ALL_CFLAGS) to use F2C_H_DIR, G2C_H_DIR, and GCC_H_DIR
  50         macros.  Remove F2C_H macro, replace use with explicit
  51         dependencies on f2c.h and g2c.h.
  52         (*clean): Remove.
  53
  54 1998-05-20  Dave Love  <d.love@dl.ac.uk>
  55
  56         * Makefile.in ($(lib)): Use shell loop instead of unportable
  57         make variable substitution.
  58
  59 Tue May 19 12:50:27 1998  Craig Burley  <burley@gnu.org>
  60
  61         Break up main() into separate .o's so making and
  62         linking against shared libraries with non-Fortran
  63         main() routines is easier:
  64         * Makefile.in (MISC): Add setarg.o and setsig.o.
  65         * libF77/Makefile.in (MISC): Ditto.
  66         * libF77/setarg.c: New file, contains f_setarg().
  67         * libF77/setsig.c: New file, contains f_setsig().
  68         * libF77/getarg_.c: Rename xarg* to f__xarg*.
  69         * libF77/iargc_.c: Ditto
  70
  71 Sat May  2 16:44:46 1998  Craig Burley  <burley@gnu.org>

  74         libI77/wsfe.c: Tweaks to eliminate unnecessary
  75         differences vs. netlib libf2c.

  92
  93         * libU77/hostnm_.c (G77_hostnm_0): Fix off-by-one error
  94         that was trashing the byte just beyond the CHARACTER*(*)
  95         argument.
  96
  97 Wed Mar  4 16:32:46 1998  Craig Burley  <burley@gnu.org>
  98
  99         * libU77/u77-test.f: Don't bother declaring etime.
 100         Use `implicit none' and declare mask and lenstr.
 101         Do ETIME/DTIME consistency check before loop, then
 102         use loop to verify that dtime "ticks" at some point.
 103         Check ETIME array-sum using single-precision add, to
 104         avoid spurious complaint on systems (like x86) that
 105         use more precision for intermediate results.
 106         Fix `Results of ETIME and DTIME...' message to print
 107         pertinent values (r1 and r2 instead of i and j).
 108         Change loop from 10M to 1K repeated up to 1000 times
 109         or until dtime "ticks".
 110         Print the number of 1K loops needed to see this tick.
 111         Answer a commented question.
 112         Split up a long line of output and do other prettying.
 113         Preset lognam in case GETLOG fails to overwrite it.
 114

 116
 117         * libI77/open.c (f_open): Use sizeof(buf) instead of

 121
 122         * libF77/signal_.c (G77_signal_0): Return type is
 123         now `void *', to cope with returning previous signal
 124         handler on 64-bit systems like Alphas.
 125         * f2cext.c (signal_): Changed accordingly.
 126

 132
 133         * libI77/close.c (f_exit): Reset f__init so that f_clos does not

 142 1997-10-03  Dave Love  <d.love@dl.ac.uk>
 143
 144         * configure.in: Check for tempnam (best because it obeys TMPDIR).

 153         length of format string.
 154         (f__fatal): Use new variable to limit length of printed string.
 155         * libI77/fmt.c (f_s): Don't skip spaces after closing paren,
 156         so nicer message results (and nested case already skips them).
 157         (pars_f): Record operating length of format string as indicated
 158         by a successful call to f_s, or ad-hoc-calculate it if failure,
 159         limiting the length to 80 characters (and stopping at NUL).
 160         (do_fio): Use new variable to limit length of printed string.
 161         * libI77/fmt.h (f__fmtlen): Declare new variable.

 175
 176         * libU77/dtime_.c (G77_dtime_0): Fix types in HAVE_GETRUSAGE case

 184
 185         * libI77/close.c (f_exit): Fix thinko, inverted test

 199
 200         * Makefile.in (stamp-lib): Put all f2cext.c objects in

 202         once into libf2c.a, to get the job done a bit faster.
 203         Still remove the objects (and libE77 directory) afterward.
 204

 214         dbesyn_): All of these return `double', not `doublereal',
 215         as they either have `float' or `double' results.

 217         besyn_): Ditto.
 218         * libU77/dbes.c (dbesj0_, dbesj1_, dbesjn_, dbesy0_, dbesy1_,

 264
 265         * libU77/alarm_.c: Delete third `status' argument,

 267         status value as function result for caller.
 268
 269         * configure.in: Rename `ac_cv_struct_FILE' to
 270         `g77_cv_struct_FILE' according to 1997-06-26 change.

 289
 290 Tue Jun 24 18:50:06 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 291

 303
 304         * libI77/rsne.c (nl_init): Don't call f_init() here,

 311
 312         * libI77/fio.h (err): Mark I/O as no longer in progress
 313         before returning a non-zero error indicator (since
 314         that tells the caller to jump over the remaining I/O
 315         calls, including the corresponding `e_whatever' call).
 316         * libI77/err.c (endif): Ditto.

 318         * libI77/lread.c (ERR): Ditto.
 319         * libI77/lread.c (l_read): Ditto by having quad case

 323
 324         * libI77/open.c (fk_open): Temporarily turn off

 330         * err.c, close.c, rewind.c, inquire.c, backspace.c, endfile.c,
 331         iio.c, open.c, Version.c, sfe.c, wsle.c, rsne.c, sue.c, rsfe.c,
 332         lread.c, wsfe.c, fio.h, due.c, dfe.c: Change f__init from
 333         `flag' to `int' and to signal not just whether initialization
 334         has happened (bit 0), but also whether I/O is in progress
 335         already (bit 1).  Consistently produce a clear diagnostic
 336         in cases of recursive I/O.  Avoid infinite recursion in
 337         f__fatal, in case sig_die triggers another error.  Don't
 338         output info on internals if not initialized in f__fatal.  Don't
 339         bother closing units in f_exit if initialization hasn't
 340         happened.

 343
 344         Update to Netlib version of 1997-06-09:
 345         * libI77/err.c, libI77/lread.c, libI77/rdfmt.c,
 346         libI77/wref.c: Move some #include's around.

 349
 350         * libU77/kill_.c (kill_): KR_headers version needed
 351         `*' in front of args in decls.
 352
 353 Sun May 25 03:16:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 354
 355         Update to Netlib version of 1997-05-24:
 356         * libF77/README, libF77/Version.c, libF77/main.c,
 357         libF77/makefile, libF77/s_paus.c, libF77/signal1.h,

 360         libI77/err.c, libI77/fmt.c, libI77/makefile,
 361         libI77/rawio.h: Apply many, but not all, of the changes
 362         made to libf2c since last update.
 363         * libF77/Makefile.in (MISC), Makefile.in (MISC): Rename
 364         exit.o to exit_.o to go along with Netlib.
 365         * libF77/signal.c: Make the prologue much simpler than
 366         Netlib has it.
 367
 368 Sun May 18 20:56:02 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 369
 370         * libU77/unlink_.c, libU77/stat_.c, libU77/symlnk_.c,
 371         libU77/chmod_.c: g_char first arg is const.
 372
 373         * libU77/chmod_.c: s_cat expects ftnlen[], not int[] or
 374         integer[], change types of array and variables
 375         accordingly.
 376
 377 May 7 1997  Daniel Pettet  <dan.pettet@bchydro.bc.ca>
 378
 379         * libU77/dbes_.c: Commented out the code in the
 380         same way the bes* routines are commented out.  This
 381         was done because corresponding C routines are referenced
 382         directly in com-rt.def.

 411         libU77/vxttime_.c: Completed renaming routines that are directly
 412         callable from g77 to internal names of the form
 413         G77_xxxx_0 that are known as intrinsics by g77.
 414
 415 Apr 8 1997  Daniel Pettet  <dan.pettet@bchydro.bc.ca>
 416
 417         * Makefile.in: Add libU77/mclock_.o and libU77/symlnk_.o to UOBJ.

 420         Add mclock_.o dependency.
 421
 422 Apr 8 1997  Daniel Pettet  <dan.pettet@bchydro.bc.ca>
 423
 424         * libU77/symlnk_.c: Added a couple of (char*) casts to malloc
 425         to silence the compiler.
 426
 427 1997-03-17  Dave Love  <d.love@dl.ac.uk>

 436
 437 Mon Mar 10 00:19:17 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 438
 439         * libI77/uio.c (do_ud) [PAD_UDread]: Add semicolon to err()
 440         invocation when macro not defined (from Mumit Khan
 441         <khan@xraylith.wisc.edu>).
 442
 443 Fri Feb 28 13:16:50 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 444
 445         * Version 0.5.20 released.
 446
 447 Wed Feb 26 20:28:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 448
 449         * Makefile.in: $(MAKE) invocations now explicitly
 450         specify `-f Makefile', just in case the `makefile's
 451         from the netlib distribution would get used instead.
 452
 453 Mon Feb 24 16:43:39 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 454
 455         * libU77/Makefile.in (check): Specify driver, and
 456         don't bother enabling already-enabled intrinsic groups.
 457         Also, get the $(srcdir) version of u77-test.f.
 458
 459 Sat Feb 22 14:08:42 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 460
 461         * libU77/u77-test.f: Explicitly declare intrinsics, get
 462         rid of useless CHARACTER declarations on intrinsics (maybe
 463         someday appropriate to implement meaning of that in g77
 464         and restore them?).
 465         Add spin loop just to fatten up the timings a bit.
 466         Clarify ETIME output as having three fields.
 467         Call TIME with CHARACTER*8, not CHARACTER*6, argument.
 468         Call new SECOND intrinsic subroutine, after calling
 469         new DUMDUM subroutine just to ensure the correct value
 470         doesn't get left around in a register or something.
 471
 472 Thu Feb 20 15:22:42 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 473
 474         * libU77/bes.c: Comment out all the code, as g77 avoids actually
 475         calling it, going directly to the system's library instead.
 476
 477 Mon Feb 17 02:27:41 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 478
 479         * libU77/fgetc_.c (fgetc_): Allow return value to be
 480         CHARACTER*(*), properly handle CHARACTER*0 and blank-pad
 481         CHARACTER*n where n>1.
 482
 483 Tue Feb 11 14:12:19 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 484
 485         * Makefile.in: Clarify role of $(srcdir) here.  Fix
 486         various targets accordingly.  Don't rely at all on
 487         gcc/f/include/ being a link to gcc/include/ -- just
 488         use it directly.
 489         (${srcdir}/configure, ${srcdir}/libU77/configure):
 490         Remove the config.cache files in build directory before
 491         cd'ing to source directory as well.
 492
 493         * libF77/Makefile.in, libI77/Makefile.in (ALL_CFLAGS):
 494         Include `-I.' to pick up build directory.
 495         Use gcc/include/ directly.
 496         * libU77/Makefile.in (ALL_CFLAGS): Include `-I$(srcdir)'
 497         to pick up source directory.
 498         (OBJS): Fix typo in `chmod_.o' (was `chmod.o').
 499
 500 Mon Feb 10 12:54:47 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 501
 502         * Makefile.in (UOBJ), libU77/Makefile.in (OBJS): Add
 503         libU77/chmod_.o to list of objects.
 504         * libU77/chmod_.c: Fix up headers.
 505         Fix implementation to not prematurely truncate command
 506         string and make room for trailing null.
 507
 508         * libU77/ctime_.c: Incoming xstime argument is now longint.
 509         * libU77/mclock_.c: Now returns longint.
 510         * libU77/time_.c: Now returns longint.
 511
 512 1997-02-10  Dave Love  <d.love@dl.ac.uk>
 513
 514         * etime_.c, dtime_.c: Typo rounded times to seconds.
 515
 516         * date_.c: Add missing return.
 517
 518         * hostnm_.c: #include unistd.h.
 519
 520 Sat Feb  8 03:30:19 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 521
 522         INTEGER*8 support built in to f2c.h and libf2c (since
 523         gcc will be used to compile relevant code anyway):
 524         * Makefile.in, libF77/Makefile.in: Add pow_qq.o,
 525         qbitbits.o, and qbitshft.o to $POW and $F90BIT macros,
 526         as appropriate.
 527         * f2c.h.in: Define appropriate types and macros.
 528         Place #error directive correctly.
 529         * configure.in: Determine appropriate types for long
 530         integer (F2C_LONGINT).
 531         Meanwhile, quote strings in #error, for consistency.
 532         Fix restoring of ac_cpp macro.
 533         * configure: Regenerated using autoconf-2.12.
 534
 535         * libF77/Version.c, libI77/Version.c, libU77/Version.c:
 536         Update version numbers.
 537         Change names and code for g77-specific version-printing
 538         routines (shorter names should be safer to link on
 539         weird, 8-char systems).
 540
 541         * libF77/c_cos.c, libF77/c_div.c, libF77/c_exp.c,
 542         libF77/c_log.c, libF77/c_sin.c, libF77/c_sqrt.c,
 543         libF77/d_cnjg.c, libF77/pow_zi.c, libF77/r_cnjg.c,
 544         libF77/z_cos.c, libF77/z_div.c, libF77/z_exp.c,
 545         libF77/z_log.c, libF77/z_sin.c, libF77/z_sqrt.c:
 546         Changed to work properly even when result is aliased
 547         with any inputs.
 548
 549         * libF77/makefile, libI77/makefile: Leave these in
 550         the g77 distribution, so it is easier to track changes
 551         to official libf2c.
 552
 553         * libF77/signal_.c: Eliminate redundant `return 0;'.
 554
 555         * libI77/fio.h (err, errfl): Fix these so they work
 556         (and must be expressed) as statements.
 557         Fix up many users of err() to include trailing semicolon.
 558
 559         * Incorporate changes by Bell Labs to libf2c through 1997-02-07.
 560
 561 1997-02-06  Dave Love  <d.love@dl.ac.uk>
 562
 563         * libU77/etime_.c, libU77/dtime_.c: Fix getrusage stuff.
 564
 565         * libU77/config.h.in: Regenerate for HAVE_GETRUSAGE.
 566
 567         * libU77/Makefile.in, libI77/Makefile.in, libF77/Makefile.in:
 568         Redo *clean targets; distclean and maintainer-clean remove the stage?
 569         and include links.  This probably want looking at further.
 570
 571 Wed Feb  5 00:21:23 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 572
 573         Add libU77 library from Dave Love <d.love@dl.ac.uk>:
 574         * Makefile.in: Add libU77 directory, rules, etc.
 575         * configure.in: New libU77 directory, Makefile, etc.
 576
 577         * Makefile.in, libF77/Makefile.in, libI77/Makefile.in,
 578         libU77/Makefile.in: Reorganize these so $(AR) commands
 579         handled by the top-level Makefile instead of the
 580         subordinates.  This permits it to do $(AR) only when
 581         one or more object files actually change, instead of
 582         having to force-update it as was necessary before.
 583         And that had the disadvantage of requiring, e.g., user
 584         root to have access to $(AR) to the library simply to
 585         install g77, which might be problematic on an NFS setup.
 586         (mostlyclean, clean, distclean, maintainer-clean):
 587         Properly handle these rules.
 588
 589         * Makefile.in: Don't invoke config.status here -- let
 590         compiler-level stuff handle all that.
 591
 592         * libI77/err.c [MISSING_FILE_ELEMS]: Declare malloc in this case
 593         too, so it doesn't end up as an integer.
 594
 595 Sat Feb  1 02:43:48 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 596
 597         * libF77/Makefile.in: More fixup for $(F90BIT) -- wasn't
 598         in list for ar command, and it wasn't correctly listed
 599         in the list of things depending on f2c.h.
 600
 601         * f2c.h.in: Fix up #error directive.
 602
 603 1997-01-31  Dave Love  <d.love@dl.ac.uk>
 604
 605         * libF77/Makefile.in ($(lib)): Add $(F90BIT); shouldn't exclude
 606         stuff f2c needs so we can share the library.
 607
 608 Sat Jan 18 19:39:03 1997  Craig Burley  <burley@gnu.ai.mit.edu>
 609
 610         * configure.in: No longer define ALWAYS_FLUSH, the
 611         resulting performance is too low.
 612
 613 Wed Dec 18 12:06:02 1996  Craig Burley  <burley@gnu.ai.mit.edu>
 614
 615         Patch from Mumit Khan <khan@xraylith.wisc.edu>:
 616         * libF77/s_paus.c: Add __CYGWIN32__ to list of macros
 617         controlling how to pause.
 618
 619 Sun Dec  1 21:25:27 1996  Craig Burley  <burley@gnu.ai.mit.edu>
 620
 621         * configure: Regenerated using autoconf-2.12.
 622
 623 Mon Nov 25 21:16:15 1996  Craig Burley  <burley@gnu.ai.mit.edu>
 624
 625         * configure: Regenerated using autoconf-2.11.
 626
 627 1996-11-19  Dave Love  <d.love@dl.ac.uk>
 628
 629         * libI77/backspace.c: Include sys/types.h for size_t.
 630
 631 Wed Nov  6 14:17:27 1996  Craig Burley  <burley@gnu.ai.mit.edu>
 632
 633         * f2c.h.in: Properly comment out the unsupported stuff so
 634         we don't get build-time errors.
 635
 636         * libF77/Version.c, libI77/Version.c: Restore macro definition
 637         of version information.
 638
 639         * libI77/Makefile.in (OBJ): Add ftell_.o to list of objects.
 640
 641         * libI77/uio.c (do_ud): Fix up casts in PAD_UDread case just
 642         like they were fixed in the other case.
 643
 644 Thu Oct 31 22:27:45 1996  Craig Burley  <burley@gnu.ai.mit.edu>
 645
 646         * libI77/ftell_.c (fseek_): Map incoming whence argument to
 647         system's actual SEEK_CUR, SEEK_SET, or SEEK_END macro for
 648         fseek(), and crash (gracefully) if the argument is invalid.
 649

 762

 778         in case just doing an install and installer has no write
 779         access to library (this is a kludge fix -- perhaps install
 780         targets should never try updating anything?).
 781
 782 Sat Nov 18 19:37:22 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 783
 784         * Version 0.5.17 released.
 785

 788         * Incorporate changes by AT&T/Bellcore to libf2c through 1995-11-15.
 789
 790 Fri Sep 22 02:19:59 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 791
 792         * libI77/backspace.c, libI77/close.c, libI77/endfile.c,
 793         libI77/fio.h, libI77/inquire.c, libI77/rawio.h,
 794         libF77/s_paus.c: Not an MSDOS system if GO32
 795         is defined, in the sense that the run-time environment
 796         is thus more UNIX-like.
 797
 798 Wed Sep 20 02:24:51 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 799
 800         * libF77/Makefile.in, libI77/Makefile.in: Comment out `ld -r -x'
 801         and `mv' line pairs, since `-x' isn't supported on systems
 802         such as Solaris, and these lines don't seem to do anything
 803         useful after all.
 804
 805 Wed Aug 30 15:58:35 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 806
 807         * Version 0.5.16 released.

 810
 811 Mon Aug 28 12:50:34 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 812
 813         * libF77/Makefile.in, libI77/Makefile.in ($(lib)): Force ar'ing
 814         and ranlib'ing of libf2c.a, else after rm'ing libf2c.a and
 815         doing a make, only libI77 or libF77 would be added to
 816         the newly created archive.
 817         Also, instead of `$?' list all targets explicitly so all
 818         objects are updated in libf2c.a even if only one actually
 819         needs recompiling, for similar reason -- we can't easily tell
 820         if a given object is really up-to-date in libf2c.a, or even
 821         present there.
 822
 823 Sun Aug 27 14:54:24 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 824
 825         * libF77/Makefile.in, libI77/Makefile.in: Fix spacing so
 826         initial tabs are present in all appropriate places.
 827         Move identical $(AR) commands in if then/else clauses
 828         to single command preceding if.
 829         (.c.o, Version[FI].o): Use $@ instead of $* because AIX (RS/6000)
 830         says $@ means source, not object, basename, and $@ seems to work
 831         everywhere.
 832
 833 Wed Aug 23 15:44:25 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 834
 835         * libF77/system_.c (system_): Declare as returning `ftnint',
 836         consistent with signal_, instead of defaulting to `int'.
 837         Hope dmg@research.att.com agrees, else probably will
 838         change to whatever he determines is correct (and change
 839         g77 accordingly).
 840
 841 Thu Aug 17 08:46:17 1995  Craig Burley  (burley@gnu.ai.mit.edu)

 850 Wed Aug 16 17:33:06 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 851
 852         * libF77/Makefile.in, libI77/Makefile.in (CFLAGS): Put -g1
 853         after configured CFLAGS but before GCC_CFLAGS, so by default
 854         the libraries are built with minimal debugging information.
 855
 856 Fri Jul 28 10:30:15 1995  Dave Love  <d.love@dl.ac.uk>
 857
 858         * libI77/open.c (f_open): Call f_init if not already done.
 859
 860 Sat Jul  1 19:31:56 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 861
 862         * libF77/system_.c (system_): Make buff one byte bigger so
 863         following byte doesn't get overwritten by call with large
 864         string.
 865
 866 Tue Jun 27 23:28:16 1995  Craig Burley  (burley@gnu.ai.mit.edu)

 872
 873         * libI77/Version.c (__G77_LIBI77_VERSION__): Add this string
 874         to track g77 mods to libf2c.
 875
 876         * libI77/rawio.h: #include <rawio.h> only conditionally,
 877         using macro intended for that purpose.
 878
 879 Fri May 19 11:20:00 1995  Craig Burley  (burley@gnu.ai.mit.edu)
 880
 881         * configure.in: Incorporate change made by d.love,
