1336 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1337
1338 Usage: $0 [OPTION]... [VAR=VALUE]...
1339
1340 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1341 VAR=VALUE.  See below for descriptions of some of the useful variables.
1342
1343 Defaults for the options are specified in brackets.
1344
1345 Configuration:
1346   -h, --help              display this help and exit
1347       --help=short        display options specific to this package
1348       --help=recursive    display the short help of all the included packages
1349   -V, --version           display version information and exit
1350   -q, --quiet, --silent   do not print \`checking ...' messages
1351       --cache-file=FILE   cache test results in FILE [disabled]
1352   -C, --config-cache      alias for \`--cache-file=config.cache'
1353   -n, --no-create         do not create output files
1354       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1355
1356 Installation directories:
1357   --prefix=PREFIX         install architecture-independent files in PREFIX
1358                           [$ac_default_prefix]
1359   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1360                           [PREFIX]
1361
1362 By default, \`make install' will install all the files in
1363 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1364 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1365 for instance \`--prefix=\$HOME'.
1366
1367 For better control, use the options below.
1368
1369 Fine tuning of the installation directories:
1370   --bindir=DIR            user executables [EPREFIX/bin]
1371   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1446 Some influential environment variables:
1447   CC          C compiler command
1448   CFLAGS      C compiler flags
1449   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1450               nonstandard directory <lib dir>
1451   LIBS        libraries to pass to the linker, e.g. -l<library>
1452   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1453               you have headers in a nonstandard directory <include dir>
1454   CXX         C++ compiler command
1455   CXXFLAGS    C++ compiler flags
1456   CPP         C preprocessor
1457
1458 Use these variables to override the choices made by `configure' or to help
1459 it to find libraries and programs with nonstandard names/locations.

7782    Here is a matrix of mmap possibilities:
7783         mmap private not fixed
7784         mmap private fixed at somewhere currently unmapped
7785         mmap private fixed at somewhere already mapped
7786         mmap shared not fixed
7787         mmap shared fixed at somewhere currently unmapped
7788         mmap shared fixed at somewhere already mapped
7789    For private mappings, we should verify that changes cannot be read()
7790    back from the file, nor mmap's back from the file at a different
7791    address.  (There have been systems where private was not correctly
7792    implemented like the infamous i386 svr4.0, and systems where the
7793    VM page cache was not coherent with the file system buffer cache
7794    like early versions of FreeBSD and possibly contemporary NetBSD.)
7795    For shared mappings, we should conversely verify that changes get
7796    propagated back to all the places they're supposed to be.
7797
7798    Grep wants private fixed already mapped.
7799    The main things grep needs to know about mmap are:
7800    * does it exist and is it safe to write into the mmap'd area
7801    * how to use it (BSD variants)  */
