1268 \`configure' configures this package to adapt to many kinds of systems.

1270 Usage: $0 [OPTION]... [VAR=VALUE]...
1271
1272 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1273 VAR=VALUE.  See below for descriptions of some of the useful variables.
1274
1275 Defaults for the options are specified in brackets.
1276
1277 Configuration:
1278   -h, --help              display this help and exit
1279       --help=short        display options specific to this package
1280       --help=recursive    display the short help of all the included packages
1281   -V, --version           display version information and exit
1282   -q, --quiet, --silent   do not print \`checking ...' messages
1283       --cache-file=FILE   cache test results in FILE [disabled]
1284   -C, --config-cache      alias for \`--cache-file=config.cache'
1285   -n, --no-create         do not create output files
1286       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1287
1288 Installation directories:
1289   --prefix=PREFIX         install architecture-independent files in PREFIX
1290                           [$ac_default_prefix]
1291   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1292                           [PREFIX]
1293
1294 By default, \`make install' will install all the files in
1295 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1296 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1297 for instance \`--prefix=\$HOME'.
1298
1299 For better control, use the options below.

1347 Optional Packages:
1348   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1349   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1350   --with-target-subdir=SUBDIR      Configuring in a subdirectory for target
1351   --with-build-subdir=SUBDIR       Configuring in a subdirectory for build
1352   --with-cross-host=HOST           Configuring with a cross compiler
1353   --with-newlib                    Configuring with newlib
1354
1355 Some influential environment variables:
1356   CC          C compiler command
1357   CFLAGS      C compiler flags
1358   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1359               nonstandard directory <lib dir>
1360   LIBS        libraries to pass to the linker, e.g. -l<library>
1361   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1362               you have headers in a nonstandard directory <include dir>
1363   CPP         C preprocessor
1364
1365 Use these variables to override the choices made by `configure' or to help
1366 it to find libraries and programs with nonstandard names/locations.

7603    Here is a matrix of mmap possibilities:
7604         mmap private not fixed
7605         mmap private fixed at somewhere currently unmapped
7606         mmap private fixed at somewhere already mapped
7607         mmap shared not fixed
7608         mmap shared fixed at somewhere currently unmapped
7609         mmap shared fixed at somewhere already mapped
7610    For private mappings, we should verify that changes cannot be read()
7611    back from the file, nor mmap's back from the file at a different
7612    address.  (There have been systems where private was not correctly
7613    implemented like the infamous i386 svr4.0, and systems where the
7614    VM page cache was not coherent with the file system buffer cache
7615    like early versions of FreeBSD and possibly contemporary NetBSD.)
7616    For shared mappings, we should conversely verify that changes get
7617    propagated back to all the places they're supposed to be.
7618
7619    Grep wants private fixed already mapped.
7620    The main things grep needs to know about mmap are:
7621    * does it exist and is it safe to write into the mmap'd area
7622    * how to use it (BSD variants)  */
