1335 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1336
1337 Usage: $0 [OPTION]... [VAR=VALUE]...
1338
1339 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1340 VAR=VALUE.  See below for descriptions of some of the useful variables.
1341
1342 Defaults for the options are specified in brackets.
1343
1344 Configuration:
1345   -h, --help              display this help and exit
1346       --help=short        display options specific to this package
1347       --help=recursive    display the short help of all the included packages
1348   -V, --version           display version information and exit
1349   -q, --quiet, --silent   do not print \`checking ...' messages
1350       --cache-file=FILE   cache test results in FILE [disabled]
1351   -C, --config-cache      alias for \`--cache-file=config.cache'
1352   -n, --no-create         do not create output files
1353       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1354
1355 Installation directories:
1356   --prefix=PREFIX         install architecture-independent files in PREFIX
1357                           [$ac_default_prefix]
1358   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1359                           [PREFIX]
1360
1361 By default, \`make install' will install all the files in
1362 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1363 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1364 for instance \`--prefix=\$HOME'.
1365
1366 For better control, use the options below.
1367
1368 Fine tuning of the installation directories:
1369   --bindir=DIR            user executables [EPREFIX/bin]
1370   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1445 Some influential environment variables:
1446   CC          C compiler command
1447   CFLAGS      C compiler flags
1448   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1449               nonstandard directory <lib dir>
1450   LIBS        libraries to pass to the linker, e.g. -l<library>
1451   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1452               you have headers in a nonstandard directory <include dir>
1453   CXX         C++ compiler command
1454   CXXFLAGS    C++ compiler flags
1455   CPP         C preprocessor
1456
1457 Use these variables to override the choices made by `configure' or to help
1458 it to find libraries and programs with nonstandard names/locations.

7781    Here is a matrix of mmap possibilities:
7782         mmap private not fixed
7783         mmap private fixed at somewhere currently unmapped
7784         mmap private fixed at somewhere already mapped
7785         mmap shared not fixed
7786         mmap shared fixed at somewhere currently unmapped
7787         mmap shared fixed at somewhere already mapped
7788    For private mappings, we should verify that changes cannot be read()
7789    back from the file, nor mmap's back from the file at a different
7790    address.  (There have been systems where private was not correctly
7791    implemented like the infamous i386 svr4.0, and systems where the
7792    VM page cache was not coherent with the file system buffer cache
7793    like early versions of FreeBSD and possibly contemporary NetBSD.)
7794    For shared mappings, we should conversely verify that changes get
7795    propagated back to all the places they're supposed to be.
7796
7797    Grep wants private fixed already mapped.
7798    The main things grep needs to know about mmap are:
7799    * does it exist and is it safe to write into the mmap'd area
7800    * how to use it (BSD variants)  */
