 791 Usage: $0 [OPTION]... [VAR=VALUE]...
 792
 793 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 794 VAR=VALUE.  See below for descriptions of some of the useful variables.
 795
 796 Defaults for the options are specified in brackets.
 797
 798 Configuration:
 799   -h, --help              display this help and exit
 800       --help=short        display options specific to this package
 801       --help=recursive    display the short help of all the included packages
 802   -V, --version           display version information and exit
 803   -q, --quiet, --silent   do not print \`checking...' messages
 804       --cache-file=FILE   cache test results in FILE [disabled]
 805   -C, --config-cache      alias for \`--cache-file=config.cache'
 806   -n, --no-create         do not create output files
 807       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 812 Installation directories:

 816                           [PREFIX]
 817
 818 By default, \`make install' will install all the files in
 819 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 820 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 821 for instance \`--prefix=\$HOME'.
 822
 823 For better control, use the options below.

 850   CFLAGS      C compiler flags
 851   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

6572    Here is a matrix of mmap possibilities:
6573         mmap private not fixed
6574         mmap private fixed at somewhere currently unmapped
6575         mmap private fixed at somewhere already mapped
6576         mmap shared not fixed
6577         mmap shared fixed at somewhere currently unmapped
6578         mmap shared fixed at somewhere already mapped
6579    For private mappings, we should verify that changes cannot be read()
6580    back from the file, nor mmap's back from the file at a different
6581    address.  (There have been systems where private was not correctly
6582    implemented like the infamous i386 svr4.0, and systems where the
6583    VM page cache was not coherent with the file system buffer cache
6584    like early versions of FreeBSD and possibly contemporary NetBSD.)
6585    For shared mappings, we should conversely verify that changes get
6586    propagated back to all the places they're supposed to be.
6587
6588    Grep wants private fixed already mapped.
6589    The main things grep needs to know about mmap are:
6590    * does it exist and is it safe to write into the mmap'd area
6591    * how to use it (BSD variants)  */
