1331 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1332
1333 Usage: $0 [OPTION]... [VAR=VALUE]...
1334
1335 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1336 VAR=VALUE.  See below for descriptions of some of the useful variables.
1337
1338 Defaults for the options are specified in brackets.
1339
1340 Configuration:
1341   -h, --help              display this help and exit
1342       --help=short        display options specific to this package
1343       --help=recursive    display the short help of all the included packages
1344   -V, --version           display version information and exit
1345   -q, --quiet, --silent   do not print \`checking ...' messages
1346       --cache-file=FILE   cache test results in FILE [disabled]
1347   -C, --config-cache      alias for \`--cache-file=config.cache'
1348   -n, --no-create         do not create output files
1349       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1350
1351 Installation directories:
1352   --prefix=PREFIX         install architecture-independent files in PREFIX
1353                           [$ac_default_prefix]
1354   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1355                           [PREFIX]
1356
1357 By default, \`make install' will install all the files in
1358 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1359 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1360 for instance \`--prefix=\$HOME'.
1361
1362 For better control, use the options below.

1439 Some influential environment variables:
1440   CC          C compiler command
1441   CFLAGS      C compiler flags
1442   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1443               nonstandard directory <lib dir>
1444   LIBS        libraries to pass to the linker, e.g. -l<library>
1445   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1446               you have headers in a nonstandard directory <include dir>
1447   CXX         C++ compiler command
1448   CXXFLAGS    C++ compiler flags
1449   CPP         C preprocessor
1450
1451 Use these variables to override the choices made by `configure' or to help
1452 it to find libraries and programs with nonstandard names/locations.

8448    Here is a matrix of mmap possibilities:
8449         mmap private not fixed
8450         mmap private fixed at somewhere currently unmapped
8451         mmap private fixed at somewhere already mapped
8452         mmap shared not fixed
8453         mmap shared fixed at somewhere currently unmapped
8454         mmap shared fixed at somewhere already mapped
8455    For private mappings, we should verify that changes cannot be read()
8456    back from the file, nor mmap's back from the file at a different
8457    address.  (There have been systems where private was not correctly
8458    implemented like the infamous i386 svr4.0, and systems where the
8459    VM page cache was not coherent with the file system buffer cache
8460    like early versions of FreeBSD and possibly contemporary NetBSD.)
8461    For shared mappings, we should conversely verify that changes get
8462    propagated back to all the places they're supposed to be.
8463
8464    Grep wants private fixed already mapped.
8465    The main things grep needs to know about mmap are:
8466    * does it exist and is it safe to write into the mmap'd area
8467    * how to use it (BSD variants)  */
