 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 \`..']

6308    Here is a matrix of mmap possibilities:
6309         mmap private not fixed
6310         mmap private fixed at somewhere currently unmapped
6311         mmap private fixed at somewhere already mapped
6312         mmap shared not fixed
6313         mmap shared fixed at somewhere currently unmapped
6314         mmap shared fixed at somewhere already mapped
6315    For private mappings, we should verify that changes cannot be read()
6316    back from the file, nor mmap's back from the file at a different
6317    address.  (There have been systems where private was not correctly
6318    implemented like the infamous i386 svr4.0, and systems where the
6319    VM page cache was not coherent with the file system buffer cache
6320    like early versions of FreeBSD and possibly contemporary NetBSD.)
6321    For shared mappings, we should conversely verify that changes get
6322    propagated back to all the places they're supposed to be.
