1318 \`configure' configures this package to adapt to many kinds of systems.
1319
1320 Usage: $0 [OPTION]... [VAR=VALUE]...
1321
1322 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1323 VAR=VALUE.  See below for descriptions of some of the useful variables.
1324
1325 Defaults for the options are specified in brackets.
1326
1327 Configuration:
1328   -h, --help              display this help and exit
1329       --help=short        display options specific to this package
1330       --help=recursive    display the short help of all the included packages
1331   -V, --version           display version information and exit
1332   -q, --quiet, --silent   do not print \`checking ...' messages
1333       --cache-file=FILE   cache test results in FILE [disabled]
1334   -C, --config-cache      alias for \`--cache-file=config.cache'
1335   -n, --no-create         do not create output files
1336       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1337
1338 Installation directories:
1339   --prefix=PREFIX         install architecture-independent files in PREFIX
1340                           [$ac_default_prefix]
1341   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1342                           [PREFIX]
1343
1344 By default, \`make install' will install all the files in
1345 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1346 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1347 for instance \`--prefix=\$HOME'.
1348
1349 For better control, use the options below.

1428 Some influential environment variables:
1429   CC          C compiler command
1430   CFLAGS      C compiler flags
1431   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1432               nonstandard directory <lib dir>
1433   LIBS        libraries to pass to the linker, e.g. -l<library>
1434   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1435               you have headers in a nonstandard directory <include dir>
1436   CXX         C++ compiler command
1437   CXXFLAGS    C++ compiler flags
1438   CPP         C preprocessor
1439
1440 Use these variables to override the choices made by `configure' or to help
1441 it to find libraries and programs with nonstandard names/locations.

6750    Here is a matrix of mmap possibilities:
6751         mmap private not fixed
6752         mmap private fixed at somewhere currently unmapped
6753         mmap private fixed at somewhere already mapped
6754         mmap shared not fixed
6755         mmap shared fixed at somewhere currently unmapped
6756         mmap shared fixed at somewhere already mapped
6757    For private mappings, we should verify that changes cannot be read()
6758    back from the file, nor mmap's back from the file at a different
6759    address.  (There have been systems where private was not correctly
6760    implemented like the infamous i386 svr4.0, and systems where the
6761    VM page cache was not coherent with the file system buffer cache
6762    like early versions of FreeBSD and possibly contemporary NetBSD.)
6763    For shared mappings, we should conversely verify that changes get
6764    propagated back to all the places they're supposed to be.
6765
6766    Grep wants private fixed already mapped.
6767    The main things grep needs to know about mmap are:
6768    * does it exist and is it safe to write into the mmap'd area
6769    * how to use it (BSD variants)  */
