1333 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1334
1335 Usage: $0 [OPTION]... [VAR=VALUE]...
1336
1337 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1338 VAR=VALUE.  See below for descriptions of some of the useful variables.
1339
1340 Defaults for the options are specified in brackets.
1341
1342 Configuration:
1343   -h, --help              display this help and exit
1344       --help=short        display options specific to this package
1345       --help=recursive    display the short help of all the included packages
1346   -V, --version           display version information and exit
1347   -q, --quiet, --silent   do not print \`checking ...' messages
1348       --cache-file=FILE   cache test results in FILE [disabled]
1349   -C, --config-cache      alias for \`--cache-file=config.cache'
1350   -n, --no-create         do not create output files
1351       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1352
1353 Installation directories:
1354   --prefix=PREFIX         install architecture-independent files in PREFIX
1355                           [$ac_default_prefix]
1356   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1357                           [PREFIX]
1358
1359 By default, \`make install' will install all the files in
1360 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1361 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1362 for instance \`--prefix=\$HOME'.
1363
1364 For better control, use the options below.
1365
1366 Fine tuning of the installation directories:
1367   --bindir=DIR            user executables [EPREFIX/bin]
1368   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1443 Some influential environment variables:
1444   CC          C compiler command
1445   CFLAGS      C compiler flags
1446   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1447               nonstandard directory <lib dir>
1448   LIBS        libraries to pass to the linker, e.g. -l<library>
1449   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1450               you have headers in a nonstandard directory <include dir>
1451   CXX         C++ compiler command
1452   CXXFLAGS    C++ compiler flags
1453   CPP         C preprocessor
1454
1455 Use these variables to override the choices made by `configure' or to help
1456 it to find libraries and programs with nonstandard names/locations.

7779    Here is a matrix of mmap possibilities:
7780         mmap private not fixed
7781         mmap private fixed at somewhere currently unmapped
7782         mmap private fixed at somewhere already mapped
7783         mmap shared not fixed
7784         mmap shared fixed at somewhere currently unmapped
7785         mmap shared fixed at somewhere already mapped
7786    For private mappings, we should verify that changes cannot be read()
7787    back from the file, nor mmap's back from the file at a different
7788    address.  (There have been systems where private was not correctly
7789    implemented like the infamous i386 svr4.0, and systems where the
7790    VM page cache was not coherent with the file system buffer cache
7791    like early versions of FreeBSD and possibly contemporary NetBSD.)
7792    For shared mappings, we should conversely verify that changes get
7793    propagated back to all the places they're supposed to be.
7794
7795    Grep wants private fixed already mapped.
7796    The main things grep needs to know about mmap are:
7797    * does it exist and is it safe to write into the mmap'd area
7798    * how to use it (BSD variants)  */
