775 Usage: $0 [OPTION]... [VAR=VALUE]...
776
777 To assign environment variables (e.g., CC, CFLAGS...), specify them as
778 VAR=VALUE. See below for descriptions of some of the useful variables.
779
780 Defaults for the options are specified in brackets.
781
782 Configuration:
783 -h, --help display this help and exit
784 --help=short display options specific to this package
785 --help=recursive display the short help of all the included packages
786 -V, --version display version information and exit
787 -q, --quiet, --silent do not print \`checking...' messages
788 --cache-file=FILE cache test results in FILE [disabled]
789 -C, --config-cache alias for \`--cache-file=config.cache'
790 -n, --no-create do not create output files

30733 Here is a matrix of mmap possibilities:
30734 mmap private not fixed
30735 mmap private fixed at somewhere currently unmapped
30736 mmap private fixed at somewhere already mapped
30737 mmap shared not fixed
30738 mmap shared fixed at somewhere currently unmapped
30739 mmap shared fixed at somewhere already mapped
30740 For private mappings, we should verify that changes cannot be read()
30741 back from the file, nor mmap's back from the file at a different
30742 address. (There have been systems where private was not correctly
30743 implemented like the infamous i386 svr4.0, and systems where the
30744 VM page cache was not coherent with the file system buffer cache
30745 like early versions of FreeBSD and possibly contemporary NetBSD.)
30746 For shared mappings, we should conversely verify that changes get
30747 propagated back to all the places they're supposed to be.
30748
30749 Grep wants private fixed already mapped.
30750 The main things grep needs to know about mmap are:
30751 * does it exist and is it safe to write into the mmap'd area
30752 * how to use it (BSD variants) */
