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.

7792    Here is a matrix of mmap possibilities:
7793         mmap private not fixed
7794         mmap private fixed at somewhere currently unmapped
7795         mmap private fixed at somewhere already mapped
7796         mmap shared not fixed
7797         mmap shared fixed at somewhere currently unmapped
7798         mmap shared fixed at somewhere already mapped
7799    For private mappings, we should verify that changes cannot be read()
7800    back from the file, nor mmap's back from the file at a different
7801    address.  (There have been systems where private was not correctly
7802    implemented like the infamous i386 svr4.0, and systems where the
7803    VM page cache was not coherent with the file system buffer cache
7804    like early versions of FreeBSD and possibly contemporary NetBSD.)
7805    For shared mappings, we should conversely verify that changes get
7806    propagated back to all the places they're supposed to be.
7807
7808    Grep wants private fixed already mapped.
7809    The main things grep needs to know about mmap are:
7810    * does it exist and is it safe to write into the mmap'd area
7811    * how to use it (BSD variants)  */
