-can be built and installed with the @code{ALWAYS_FLUSH} macro defined.
+Some Fortran programs require output
+(writes) to be flushed to the operating system (under UNIX,
+via the @code{fflush()} library call) so that errors,
+such as disk full, are immediately flagged via the relevant
+@code{ERR=} and @code{IOSTAT=} mechanism, instead of such
+errors being flagged later as subsequent writes occur, forcing
+the previously written data to disk, or when the file is
+closed.
+
+Essentially, the difference can be viewed as synchronous error
+reporting (immediate flagging of errors during writes) versus
+asynchronous, or, more precisely, buffered error reporting
+(detection of errors might be delayed).
+
+@code{libg2c} supports flagging write errors immediately when
+it is built with the @code{ALWAYS_FLUSH} macro defined.
+This results in a @code{libg2c} that runs slower, sometimes
+quite a bit slower, under certain circumstances---for example,
+accessing files via the networked file system NFS---but the
+effect can be more reliable, robust file I/O.
+
+If you know that Fortran programs requiring this level of precision
+of error reporting are to be compiled using the
+version of @code{g77} you are building, you might wish to
+modify the @code{g77} source tree so that the version of
+@code{libg2c} is built with the @code{ALWAYS_FLUSH} macro
+defined, enabling this behavior.
+
+To do this, find this line in @file{@value{path-libf2c}/f2c.h} in
+your @code{g77} source tree:
+
+@example
+/* #define ALWAYS_FLUSH */
+@end example
+

@node Large File Unit Numbers
@subsection Large File Unit Numbers
If you can easily change your program to use unit numbers
in the range 0 through 99, you should do so.
-Otherwise, see @ref{Larger File Unit Numbers}, for information on how
-to change @code{MXUNIT} in @code{libg2c} so you can build and
-install a new version of @code{libg2c} that supports the larger
-unit numbers you need.
+As distributed, whether as part of @code{f2c} or @code{g77},
+@code{libf2c} accepts file unit numbers only in the range
+0 through 99.
+For example, a statement such as @samp{WRITE (UNIT=100)} causes
+a run-time crash in @code{libf2c}, because the unit number,
+100, is out of range.
-@emph{Note:} While @code{libg2c} places a limit on the range
-of Fortran file-unit numbers, the underlying library and operating
-system might impose different kinds of limits.
-For example, some systems limit the number of files simultaneously
-open by a running program.
-Information on how to increase these limits should be found
+If you know that Fortran programs at your installation require
+the use of unit numbers higher than 99, you can change the
+value of the @code{MXUNIT} macro, which represents the maximum unit
+number, to an appropriately higher value.
+
+To do this, edit the file @file{@value{path-libf2c}/libI77/fio.h} in your
+@code{g77} source tree, changing the following line:
+
+@example
+#define MXUNIT 100
+@end example
+
+Change the line so that the value of @code{MXUNIT} is defined to be
+at least one @emph{greater} than the maximum unit number used by
+the Fortran programs on your system.
+
+(For example, a program that does @samp{WRITE (UNIT=255)} would require
+@code{MXUNIT} set to at least 256 to avoid crashing.)
+
+Then build or rebuild @code{g77} as appropriate.
+
+@emph{Note:} Changing this macro has @emph{no} effect on other limits
+your system might place on the number of files open at the same time.
+That is, the macro might allow a program to do @samp{WRITE (UNIT=100)},
+but the library and operating system underlying @code{libf2c} might
+disallow it if many other files have already been opened (via @code{OPEN} or
+implicitly via @code{READ}, @code{WRITE}, and so on).
+Information on how to increase these other limits should be found
in your system's documentation.

-@subsection Cross-compiler Problems
-@cindex cross-compiler, problems
-
-@code{g77} has been in alpha testing since September of
-1992, and in public beta testing since February of 1995.
-Alpha testing was done by a small number of people worldwide on a fairly
-wide variety of machines, involving self-compilation in most or
-all cases.
-Beta testing has been done primarily via self-compilation,
-but in more and more cases, cross-compilation (and ``criss-cross
-compilation'', where a version of a compiler is built on one machine
-to run on a second and generate code that runs on a third) has
-been tried and has succeeded, to varying extents.
-
-Generally, @code{g77} can be ported to any configuration to which
-@code{gcc}, @code{f2c}, and @code{libf2c} can be ported and made
-to work together, aside from the known problems described in this
-manual.
-If you want to port @code{g77} to a particular configuration,
-you should first make sure @code{gcc} and @code{libf2c} can be
-ported to that configuration before focusing on @code{g77}, because
-@code{g77} is so dependent on them.
-
-Even for cases where @code{gcc} and @code{libf2c} work,
-you might run into problems with cross-compilation on certain machines,
-for several reasons.
-
-@itemize @bullet
-@item
-There is one known bug
-(a design bug to be fixed in 0.6) that prevents configuration of
-@code{g77} as a cross-compiler in some cases,
-though there are assumptions made during
-configuration that probably make doing non-self-hosting builds
-a hassle, requiring manual intervention.
-
-@item
-@code{gcc} might still have some trouble being configured
-for certain combinations of machines.
-For example, it might not know how to handle floating-point
-constants.
-
-@item
-Improvements to the way @code{libg2c} is built could make
-building @code{g77} as a cross-compiler easier---for example,
-passing and using @samp{$(LD)} and @samp{$(AR)} in the appropriate
-ways.
-(This was improved in the @code{egcs} version of @code{g77},
-especially as of version 1.1.)
-
-@item
-There are still some challenges putting together the right
-run-time libraries (needed by @code{libg2c}) for a target
-system, depending on the systems involved in the configuration.
-(This is a general problem with cross-compilation, and with
-@code{gcc} in particular.)

-
-This size currently is quite small, since @code{g77}

-if it has a 64-bit operating system running on it).
-That was because @code{g77} was known to not work
-properly on such configurations.
-
-As of version 0.5.20, @code{g77} is believed to work well
-enough on such systems.
-So, the warning is no longer needed or provided.
-
-However, support for 64-bit systems, especially in
-areas such as cross-compilation and handling of
-intrinsics, is still incomplete.
-The symptoms
-are believed to be compile-time diagnostics rather
-than the generation of bad code.
-It is hoped that version 0.6 will completely support 64-bit
-systems.
