1501 \`configure' configures this package to adapt to many kinds of systems.
1502
1503 Usage: $0 [OPTION]... [VAR=VALUE]...
1504
1505 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1506 VAR=VALUE.  See below for descriptions of some of the useful variables.
1507
1508 Defaults for the options are specified in brackets.
1509
1510 Configuration:
1511   -h, --help              display this help and exit
1512       --help=short        display options specific to this package
1513       --help=recursive    display the short help of all the included packages
1514   -V, --version           display version information and exit
1515   -q, --quiet, --silent   do not print \`checking ...' messages
1516       --cache-file=FILE   cache test results in FILE [disabled]
1517   -C, --config-cache      alias for \`--cache-file=config.cache'
1518   -n, --no-create         do not create output files
1519       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1520
1521 Installation directories:
1522   --prefix=PREFIX         install architecture-independent files in PREFIX
1523                           [$ac_default_prefix]
1524   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1525                           [PREFIX]
1526
1527 By default, \`make install' will install all the files in
1528 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1529 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1530 for instance \`--prefix=\$HOME'.
1531
1532 For better control, use the options below.

13448    Here is a matrix of mmap possibilities:
13449         mmap private not fixed
13450         mmap private fixed at somewhere currently unmapped
13451         mmap private fixed at somewhere already mapped
13452         mmap shared not fixed
13453         mmap shared fixed at somewhere currently unmapped
13454         mmap shared fixed at somewhere already mapped
13455    For private mappings, we should verify that changes cannot be read()
13456    back from the file, nor mmap's back from the file at a different
13457    address.  (There have been systems where private was not correctly
13458    implemented like the infamous i386 svr4.0, and systems where the
13459    VM page cache was not coherent with the file system buffer cache
13460    like early versions of FreeBSD and possibly contemporary NetBSD.)
13461    For shared mappings, we should conversely verify that changes get
13462    propagated back to all the places they're supposed to be.
13463
13464    Grep wants private fixed already mapped.
13465    The main things grep needs to know about mmap are:
13466    * does it exist and is it safe to write into the mmap'd area
13467    * how to use it (BSD variants)  */
