 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

 913   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
 914               nonstandard directory <lib dir>
 915   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have

32056    Here is a matrix of mmap possibilities:
32057         mmap private not fixed
32058         mmap private fixed at somewhere currently unmapped
32059         mmap private fixed at somewhere already mapped
32060         mmap shared not fixed
32061         mmap shared fixed at somewhere currently unmapped
32062         mmap shared fixed at somewhere already mapped
32063    For private mappings, we should verify that changes cannot be read()
32064    back from the file, nor mmap's back from the file at a different
32065    address.  (There have been systems where private was not correctly
32066    implemented like the infamous i386 svr4.0, and systems where the
32067    VM page cache was not coherent with the file system buffer cache
32068    like early versions of FreeBSD and possibly contemporary NetBSD.)
32069    For shared mappings, we should conversely verify that changes get
32070    propagated back to all the places they're supposed to be.
32071
32072    Grep wants private fixed already mapped.
32073    The main things grep needs to know about mmap are:
32074    * does it exist and is it safe to write into the mmap'd area
32075    * how to use it (BSD variants)  */
