1511 \`configure' configures this package to adapt to many kinds of systems.
1512
1513 Usage: $0 [OPTION]... [VAR=VALUE]...
1514
1515 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1516 VAR=VALUE.  See below for descriptions of some of the useful variables.
1517
1518 Defaults for the options are specified in brackets.
1519
1520 Configuration:
1521   -h, --help              display this help and exit
1522       --help=short        display options specific to this package
1523       --help=recursive    display the short help of all the included packages
1524   -V, --version           display version information and exit
1525   -q, --quiet, --silent   do not print \`checking ...' messages
1526       --cache-file=FILE   cache test results in FILE [disabled]
1527   -C, --config-cache      alias for \`--cache-file=config.cache'
1528   -n, --no-create         do not create output files
1529       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1530
1531 Installation directories:
1532   --prefix=PREFIX         install architecture-independent files in PREFIX
1533                           [$ac_default_prefix]
1534   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1535                           [PREFIX]
1536
1537 By default, \`make install' will install all the files in
1538 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1539 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1540 for instance \`--prefix=\$HOME'.
1541
1542 For better control, use the options below.

1728   YFLAGS      The list of arguments that will be passed by default to $YACC.
1729               This script will default YFLAGS to the empty string to avoid a

13657    Here is a matrix of mmap possibilities:
13658         mmap private not fixed
13659         mmap private fixed at somewhere currently unmapped
13660         mmap private fixed at somewhere already mapped
13661         mmap shared not fixed
13662         mmap shared fixed at somewhere currently unmapped
13663         mmap shared fixed at somewhere already mapped
13664    For private mappings, we should verify that changes cannot be read()
13665    back from the file, nor mmap's back from the file at a different
13666    address.  (There have been systems where private was not correctly
13667    implemented like the infamous i386 svr4.0, and systems where the
13668    VM page cache was not coherent with the file system buffer cache
13669    like early versions of FreeBSD and possibly contemporary NetBSD.)
13670    For shared mappings, we should conversely verify that changes get
13671    propagated back to all the places they're supposed to be.
13672
13673    Grep wants private fixed already mapped.
13674    The main things grep needs to know about mmap are:
13675    * does it exist and is it safe to write into the mmap'd area
13676    * how to use it (BSD variants)  */
