 784
 785 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 786 VAR=VALUE.  See below for descriptions of some of the useful variables.
 787
 788 Defaults for the options are specified in brackets.
 789
 790 Configuration:
 791   -h, --help              display this help and exit
 792       --help=short        display options specific to this package
 793       --help=recursive    display the short help of all the included packages
 794   -V, --version           display version information and exit
 795   -q, --quiet, --silent   do not print \`checking...' messages
 796       --cache-file=FILE   cache test results in FILE [disabled]
 797   -C, --config-cache      alias for \`--cache-file=config.cache'
 798   -n, --no-create         do not create output files
 799       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

8643    Here is a matrix of mmap possibilities:
8644         mmap private not fixed
8645         mmap private fixed at somewhere currently unmapped
8646         mmap private fixed at somewhere already mapped
8647         mmap shared not fixed
8648         mmap shared fixed at somewhere currently unmapped
8649         mmap shared fixed at somewhere already mapped
8650    For private mappings, we should verify that changes cannot be read()
8651    back from the file, nor mmap's back from the file at a different
8652    address.  (There have been systems where private was not correctly
8653    implemented like the infamous i386 svr4.0, and systems where the
8654    VM page cache was not coherent with the file system buffer cache
8655    like early versions of FreeBSD and possibly contemporary NetBSD.)
8656    For shared mappings, we should conversely verify that changes get
8657    propagated back to all the places they're supposed to be.
8658
8659    Grep wants private fixed already mapped.
8660    The main things grep needs to know about mmap are:
8661    * does it exist and is it safe to write into the mmap'd area
8662    * how to use it (BSD variants)  */
