1496 \`configure' configures this package to adapt to many kinds of systems.
1497
1498 Usage: $0 [OPTION]... [VAR=VALUE]...
1499
1500 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1501 VAR=VALUE.  See below for descriptions of some of the useful variables.
1502
1503 Defaults for the options are specified in brackets.
1504
1505 Configuration:
1506   -h, --help              display this help and exit
1507       --help=short        display options specific to this package
1508       --help=recursive    display the short help of all the included packages
1509   -V, --version           display version information and exit
1510   -q, --quiet, --silent   do not print \`checking ...' messages
1511       --cache-file=FILE   cache test results in FILE [disabled]
1512   -C, --config-cache      alias for \`--cache-file=config.cache'
1513   -n, --no-create         do not create output files
1514       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1515
1516 Installation directories:
1517   --prefix=PREFIX         install architecture-independent files in PREFIX
1518                           [$ac_default_prefix]
1519   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1520                           [PREFIX]
1521
1522 By default, \`make install' will install all the files in
1523 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1524 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1525 for instance \`--prefix=\$HOME'.
1526
1527 For better control, use the options below.

1708   YFLAGS      The list of arguments that will be passed by default to $YACC.
1709               This script will default YFLAGS to the empty string to avoid a

12957    Here is a matrix of mmap possibilities:
12958         mmap private not fixed
12959         mmap private fixed at somewhere currently unmapped
12960         mmap private fixed at somewhere already mapped
12961         mmap shared not fixed
12962         mmap shared fixed at somewhere currently unmapped
12963         mmap shared fixed at somewhere already mapped
12964    For private mappings, we should verify that changes cannot be read()
12965    back from the file, nor mmap's back from the file at a different
12966    address.  (There have been systems where private was not correctly
12967    implemented like the infamous i386 svr4.0, and systems where the
12968    VM page cache was not coherent with the file system buffer cache
12969    like early versions of FreeBSD and possibly contemporary NetBSD.)
12970    For shared mappings, we should conversely verify that changes get
12971    propagated back to all the places they're supposed to be.
12972
12973    Grep wants private fixed already mapped.
12974    The main things grep needs to know about mmap are:
12975    * does it exist and is it safe to write into the mmap'd area
12976    * how to use it (BSD variants)  */
