1329 \`configure' configures this package to adapt to many kinds of systems.

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

10505    Here is a matrix of mmap possibilities:
10506         mmap private not fixed
10507         mmap private fixed at somewhere currently unmapped
10508         mmap private fixed at somewhere already mapped
10509         mmap shared not fixed
10510         mmap shared fixed at somewhere currently unmapped
10511         mmap shared fixed at somewhere already mapped
10512    For private mappings, we should verify that changes cannot be read()
10513    back from the file, nor mmap's back from the file at a different
10514    address.  (There have been systems where private was not correctly
10515    implemented like the infamous i386 svr4.0, and systems where the
10516    VM page cache was not coherent with the file system buffer cache
10517    like early versions of FreeBSD and possibly contemporary NetBSD.)
10518    For shared mappings, we should conversely verify that changes get
10519    propagated back to all the places they're supposed to be.
10520
10521    Grep wants private fixed already mapped.
10522    The main things grep needs to know about mmap are:
10523    * does it exist and is it safe to write into the mmap'd area
10524    * how to use it (BSD variants)  */
