 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

32016    Here is a matrix of mmap possibilities:
32017         mmap private not fixed
32018         mmap private fixed at somewhere currently unmapped
32019         mmap private fixed at somewhere already mapped
32020         mmap shared not fixed
32021         mmap shared fixed at somewhere currently unmapped
32022         mmap shared fixed at somewhere already mapped
32023    For private mappings, we should verify that changes cannot be read()
32024    back from the file, nor mmap's back from the file at a different
32025    address.  (There have been systems where private was not correctly
32026    implemented like the infamous i386 svr4.0, and systems where the
32027    VM page cache was not coherent with the file system buffer cache
32028    like early versions of FreeBSD and possibly contemporary NetBSD.)
32029    For shared mappings, we should conversely verify that changes get
32030    propagated back to all the places they're supposed to be.
32031
32032    Grep wants private fixed already mapped.
32033    The main things grep needs to know about mmap are:
32034    * does it exist and is it safe to write into the mmap'd area
32035    * how to use it (BSD variants)  */
