 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 \`..']

7469    Here is a matrix of mmap possibilities:
7470         mmap private not fixed
7471         mmap private fixed at somewhere currently unmapped
7472         mmap private fixed at somewhere already mapped
7473         mmap shared not fixed
7474         mmap shared fixed at somewhere currently unmapped
7475         mmap shared fixed at somewhere already mapped
7476    For private mappings, we should verify that changes cannot be read()
7477    back from the file, nor mmap's back from the file at a different
7478    address.  (There have been systems where private was not correctly
7479    implemented like the infamous i386 svr4.0, and systems where the
7480    VM page cache was not coherent with the file system buffer cache
7481    like early versions of FreeBSD and possibly contemporary NetBSD.)
7482    For shared mappings, we should conversely verify that changes get
7483    propagated back to all the places they're supposed to be.
7484
7485    Grep wants private fixed already mapped.
7486    The main things grep needs to know about mmap are:
7487    * does it exist and is it safe to write into the mmap'd area
7488    * how to use it (BSD variants)  */
