 783
 784 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 785 VAR=VALUE.  See below for descriptions of some of the useful variables.
 786
 787 Defaults for the options are specified in brackets.
 788
 789 Configuration:
 790   -h, --help              display this help and exit
 791       --help=short        display options specific to this package
 792       --help=recursive    display the short help of all the included packages
 793   -V, --version           display version information and exit
 794   -q, --quiet, --silent   do not print \`checking...' messages
 795       --cache-file=FILE   cache test results in FILE [disabled]
 796   -C, --config-cache      alias for \`--cache-file=config.cache'
 797   -n, --no-create         do not create output files
 798       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

6111    Here is a matrix of mmap possibilities:
6112         mmap private not fixed
6113         mmap private fixed at somewhere currently unmapped
6114         mmap private fixed at somewhere already mapped
6115         mmap shared not fixed
6116         mmap shared fixed at somewhere currently unmapped
6117         mmap shared fixed at somewhere already mapped
6118    For private mappings, we should verify that changes cannot be read()
6119    back from the file, nor mmap's back from the file at a different
6120    address.  (There have been systems where private was not correctly
6121    implemented like the infamous i386 svr4.0, and systems where the
6122    VM page cache was not coherent with the file system buffer cache
6123    like early versions of FreeBSD and possibly contemporary NetBSD.)
6124    For shared mappings, we should conversely verify that changes get
6125    propagated back to all the places they're supposed to be.
6126
6127    Grep wants private fixed already mapped.
6128    The main things grep needs to know about mmap are:
6129    * does it exist and is it safe to write into the mmap'd area
6130    * how to use it (BSD variants)  */
