1503 \`configure' configures this package to adapt to many kinds of systems.
1504
1505 Usage: $0 [OPTION]... [VAR=VALUE]...
1506
1507 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1508 VAR=VALUE.  See below for descriptions of some of the useful variables.
1509
1510 Defaults for the options are specified in brackets.
1511
1512 Configuration:
1513   -h, --help              display this help and exit
1514       --help=short        display options specific to this package
1515       --help=recursive    display the short help of all the included packages
1516   -V, --version           display version information and exit
1517   -q, --quiet, --silent   do not print \`checking ...' messages
1518       --cache-file=FILE   cache test results in FILE [disabled]
1519   -C, --config-cache      alias for \`--cache-file=config.cache'
1520   -n, --no-create         do not create output files
1521       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1522
1523 Installation directories:
1524   --prefix=PREFIX         install architecture-independent files in PREFIX
1525                           [$ac_default_prefix]
1526   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1527                           [PREFIX]
1528
1529 By default, \`make install' will install all the files in
1530 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1531 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1532 for instance \`--prefix=\$HOME'.
1533
1534 For better control, use the options below.

13547    Here is a matrix of mmap possibilities:
13548         mmap private not fixed
13549         mmap private fixed at somewhere currently unmapped
13550         mmap private fixed at somewhere already mapped
13551         mmap shared not fixed
13552         mmap shared fixed at somewhere currently unmapped
13553         mmap shared fixed at somewhere already mapped
13554    For private mappings, we should verify that changes cannot be read()
13555    back from the file, nor mmap's back from the file at a different
13556    address.  (There have been systems where private was not correctly
13557    implemented like the infamous i386 svr4.0, and systems where the
13558    VM page cache was not coherent with the file system buffer cache
13559    like early versions of FreeBSD and possibly contemporary NetBSD.)
13560    For shared mappings, we should conversely verify that changes get
13561    propagated back to all the places they're supposed to be.
13562
13563    Grep wants private fixed already mapped.
13564    The main things grep needs to know about mmap are:
13565    * does it exist and is it safe to write into the mmap'd area
13566    * how to use it (BSD variants)  */
