1500 \`configure' configures this package to adapt to many kinds of systems.
1501
1502 Usage: $0 [OPTION]... [VAR=VALUE]...
1503
1504 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1505 VAR=VALUE.  See below for descriptions of some of the useful variables.
1506
1507 Defaults for the options are specified in brackets.
1508
1509 Configuration:
1510   -h, --help              display this help and exit
1511       --help=short        display options specific to this package
1512       --help=recursive    display the short help of all the included packages
1513   -V, --version           display version information and exit
1514   -q, --quiet, --silent   do not print \`checking ...' messages
1515       --cache-file=FILE   cache test results in FILE [disabled]
1516   -C, --config-cache      alias for \`--cache-file=config.cache'
1517   -n, --no-create         do not create output files
1518       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1519
1520 Installation directories:
1521   --prefix=PREFIX         install architecture-independent files in PREFIX
1522                           [$ac_default_prefix]
1523   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1524                           [PREFIX]
1525
1526 By default, \`make install' will install all the files in
1527 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1528 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1529 for instance \`--prefix=\$HOME'.
1530
1531 For better control, use the options below.

1711   YFLAGS      The list of arguments that will be passed by default to $YACC.
1712               This script will default YFLAGS to the empty string to avoid a

13443    Here is a matrix of mmap possibilities:
13444         mmap private not fixed
13445         mmap private fixed at somewhere currently unmapped
13446         mmap private fixed at somewhere already mapped
13447         mmap shared not fixed
13448         mmap shared fixed at somewhere currently unmapped
13449         mmap shared fixed at somewhere already mapped
13450    For private mappings, we should verify that changes cannot be read()
13451    back from the file, nor mmap's back from the file at a different
13452    address.  (There have been systems where private was not correctly
13453    implemented like the infamous i386 svr4.0, and systems where the
13454    VM page cache was not coherent with the file system buffer cache
13455    like early versions of FreeBSD and possibly contemporary NetBSD.)
13456    For shared mappings, we should conversely verify that changes get
13457    propagated back to all the places they're supposed to be.
13458
13459    Grep wants private fixed already mapped.
13460    The main things grep needs to know about mmap are:
13461    * does it exist and is it safe to write into the mmap'd area
13462    * how to use it (BSD variants)  */
