1342 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1343
1344 Usage: $0 [OPTION]... [VAR=VALUE]...
1345
1346 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1347 VAR=VALUE.  See below for descriptions of some of the useful variables.
1348
1349 Defaults for the options are specified in brackets.
1350
1351 Configuration:
1352   -h, --help              display this help and exit
1353       --help=short        display options specific to this package
1354       --help=recursive    display the short help of all the included packages
1355   -V, --version           display version information and exit
1356   -q, --quiet, --silent   do not print \`checking ...' messages
1357       --cache-file=FILE   cache test results in FILE [disabled]
1358   -C, --config-cache      alias for \`--cache-file=config.cache'
1359   -n, --no-create         do not create output files
1360       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1361
1362 Installation directories:
1363   --prefix=PREFIX         install architecture-independent files in PREFIX
1364                           [$ac_default_prefix]
1365   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1366                           [PREFIX]
1367
1368 By default, \`make install' will install all the files in
1369 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1370 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1371 for instance \`--prefix=\$HOME'.
1372
1373 For better control, use the options below.
1374
1375 Fine tuning of the installation directories:
1376   --bindir=DIR            user executables [EPREFIX/bin]
1377   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1457   CC          C compiler command
1458   CFLAGS      C compiler flags
1459   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1460               nonstandard directory <lib dir>
1461   LIBS        libraries to pass to the linker, e.g. -l<library>
1462   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1463               you have headers in a nonstandard directory <include dir>
1464   CXX         C++ compiler command
1465   CXXFLAGS    C++ compiler flags
1466   CPP         C preprocessor
1467
1468 Use these variables to override the choices made by `configure' or to help
1469 it to find libraries and programs with nonstandard names/locations.

9310    Here is a matrix of mmap possibilities:
9311         mmap private not fixed
9312         mmap private fixed at somewhere currently unmapped
9313         mmap private fixed at somewhere already mapped
9314         mmap shared not fixed
9315         mmap shared fixed at somewhere currently unmapped
9316         mmap shared fixed at somewhere already mapped
9317    For private mappings, we should verify that changes cannot be read()
9318    back from the file, nor mmap's back from the file at a different
9319    address.  (There have been systems where private was not correctly
9320    implemented like the infamous i386 svr4.0, and systems where the
9321    VM page cache was not coherent with the file system buffer cache
9322    like early versions of FreeBSD and possibly contemporary NetBSD.)
9323    For shared mappings, we should conversely verify that changes get
9324    propagated back to all the places they're supposed to be.
9325
9326    Grep wants private fixed already mapped.
9327    The main things grep needs to know about mmap are:
9328    * does it exist and is it safe to write into the mmap'd area
9329    * how to use it (BSD variants)  */
