1506 \`configure' configures this package to adapt to many kinds of systems.
1507
1508 Usage: $0 [OPTION]... [VAR=VALUE]...
1509
1510 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1511 VAR=VALUE.  See below for descriptions of some of the useful variables.
1512
1513 Defaults for the options are specified in brackets.
1514
1515 Configuration:
1516   -h, --help              display this help and exit
1517       --help=short        display options specific to this package
1518       --help=recursive    display the short help of all the included packages
1519   -V, --version           display version information and exit
1520   -q, --quiet, --silent   do not print \`checking ...' messages
1521       --cache-file=FILE   cache test results in FILE [disabled]
1522   -C, --config-cache      alias for \`--cache-file=config.cache'
1523   -n, --no-create         do not create output files
1524       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1525
1526 Installation directories:
1527   --prefix=PREFIX         install architecture-independent files in PREFIX
1528                           [$ac_default_prefix]
1529   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1530                           [PREFIX]
1531
1532 By default, \`make install' will install all the files in
1533 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1534 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1535 for instance \`--prefix=\$HOME'.
1536
1537 For better control, use the options below.

13574    Here is a matrix of mmap possibilities:
13575         mmap private not fixed
13576         mmap private fixed at somewhere currently unmapped
13577         mmap private fixed at somewhere already mapped
13578         mmap shared not fixed
13579         mmap shared fixed at somewhere currently unmapped
13580         mmap shared fixed at somewhere already mapped
13581    For private mappings, we should verify that changes cannot be read()
13582    back from the file, nor mmap's back from the file at a different
13583    address.  (There have been systems where private was not correctly
13584    implemented like the infamous i386 svr4.0, and systems where the
13585    VM page cache was not coherent with the file system buffer cache
13586    like early versions of FreeBSD and possibly contemporary NetBSD.)
13587    For shared mappings, we should conversely verify that changes get
13588    propagated back to all the places they're supposed to be.
13589
13590    Grep wants private fixed already mapped.
13591    The main things grep needs to know about mmap are:
13592    * does it exist and is it safe to write into the mmap'd area
13593    * how to use it (BSD variants)  */
