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

26546 Here is a matrix of mmap possibilities:
26547 mmap private not fixed
26548 mmap private fixed at somewhere currently unmapped
26549 mmap private fixed at somewhere already mapped
26550 mmap shared not fixed
26551 mmap shared fixed at somewhere currently unmapped
26552 mmap shared fixed at somewhere already mapped
26553 For private mappings, we should verify that changes cannot be read()
26554 back from the file, nor mmap's back from the file at a different
26555 address. (There have been systems where private was not correctly
26556 implemented like the infamous i386 svr4.0, and systems where the
26557 VM page cache was not coherent with the file system buffer cache
26558 like early versions of FreeBSD and possibly contemporary NetBSD.)
26559 For shared mappings, we should conversely verify that changes get
26560 propagated back to all the places they're supposed to be.
26561
26562 Grep wants private fixed already mapped.
26563 The main things grep needs to know about mmap are:
26564 * does it exist and is it safe to write into the mmap'd area
26565 * how to use it (BSD variants) */
