1504 \`configure' configures this package to adapt to many kinds of systems.
1505
1506 Usage: $0 [OPTION]... [VAR=VALUE]...
1507
1508 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1509 VAR=VALUE.  See below for descriptions of some of the useful variables.
1510
1511 Defaults for the options are specified in brackets.
1512
1513 Configuration:
1514   -h, --help              display this help and exit
1515       --help=short        display options specific to this package
1516       --help=recursive    display the short help of all the included packages
1517   -V, --version           display version information and exit
1518   -q, --quiet, --silent   do not print \`checking ...' messages
1519       --cache-file=FILE   cache test results in FILE [disabled]
1520   -C, --config-cache      alias for \`--cache-file=config.cache'
1521   -n, --no-create         do not create output files
1522       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1523
1524 Installation directories:
1525   --prefix=PREFIX         install architecture-independent files in PREFIX
1526                           [$ac_default_prefix]
1527   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1528                           [PREFIX]
1529
1530 By default, \`make install' will install all the files in
1531 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1532 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1533 for instance \`--prefix=\$HOME'.
1534
1535 For better control, use the options below.

13567    Here is a matrix of mmap possibilities:
13568         mmap private not fixed
13569         mmap private fixed at somewhere currently unmapped
13570         mmap private fixed at somewhere already mapped
13571         mmap shared not fixed
13572         mmap shared fixed at somewhere currently unmapped
13573         mmap shared fixed at somewhere already mapped
13574    For private mappings, we should verify that changes cannot be read()
13575    back from the file, nor mmap's back from the file at a different
13576    address.  (There have been systems where private was not correctly
13577    implemented like the infamous i386 svr4.0, and systems where the
13578    VM page cache was not coherent with the file system buffer cache
13579    like early versions of FreeBSD and possibly contemporary NetBSD.)
13580    For shared mappings, we should conversely verify that changes get
13581    propagated back to all the places they're supposed to be.
13582
13583    Grep wants private fixed already mapped.
13584    The main things grep needs to know about mmap are:
13585    * does it exist and is it safe to write into the mmap'd area
13586    * how to use it (BSD variants)  */
