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

30485 mmap shared fixed at somewhere already mapped
30486 For private mappings, we should verify that changes cannot be read()
30487 back from the file, nor mmap's back from the file at a different
30488 address. (There have been systems where private was not correctly
30489 implemented like the infamous i386 svr4.0, and systems where the
30490 VM page cache was not coherent with the file system buffer cache
30491 like early versions of FreeBSD and possibly contemporary NetBSD.)
30492 For shared mappings, we should conversely verify that changes get
30493 propagated back to all the places they're supposed to be.
30494
30495 Grep wants private fixed already mapped.
30496 The main things grep needs to know about mmap are:
30497 * does it exist and is it safe to write into the mmap'd area
30498 * how to use it (BSD variants) */
