1495 \`configure' configures this package to adapt to many kinds of systems.
1496
1497 Usage: $0 [OPTION]... [VAR=VALUE]...
1498
1499 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1500 VAR=VALUE.  See below for descriptions of some of the useful variables.
1501
1502 Defaults for the options are specified in brackets.
1503
1504 Configuration:
1505   -h, --help              display this help and exit
1506       --help=short        display options specific to this package
1507       --help=recursive    display the short help of all the included packages
1508   -V, --version           display version information and exit
1509   -q, --quiet, --silent   do not print \`checking ...' messages
1510       --cache-file=FILE   cache test results in FILE [disabled]
1511   -C, --config-cache      alias for \`--cache-file=config.cache'
1512   -n, --no-create         do not create output files
1513       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1514
1515 Installation directories:
1516   --prefix=PREFIX         install architecture-independent files in PREFIX
1517                           [$ac_default_prefix]
1518   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1519                           [PREFIX]
1520
1521 By default, \`make install' will install all the files in
1522 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1523 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1524 for instance \`--prefix=\$HOME'.
1525
1526 For better control, use the options below.

12986    Here is a matrix of mmap possibilities:
12987         mmap private not fixed
12988         mmap private fixed at somewhere currently unmapped
12989         mmap private fixed at somewhere already mapped
12990         mmap shared not fixed
12991         mmap shared fixed at somewhere currently unmapped
12992         mmap shared fixed at somewhere already mapped
12993    For private mappings, we should verify that changes cannot be read()
12994    back from the file, nor mmap's back from the file at a different
12995    address.  (There have been systems where private was not correctly
12996    implemented like the infamous i386 svr4.0, and systems where the
12997    VM page cache was not coherent with the file system buffer cache
12998    like early versions of FreeBSD and possibly contemporary NetBSD.)
12999    For shared mappings, we should conversely verify that changes get
13000    propagated back to all the places they're supposed to be.
13001
13002    Grep wants private fixed already mapped.
13003    The main things grep needs to know about mmap are:
13004    * does it exist and is it safe to write into the mmap'd area
13005    * how to use it (BSD variants)  */
