1486 \`configure' configures this package to adapt to many kinds of systems.
1487
1488 Usage: $0 [OPTION]... [VAR=VALUE]...
1489
1490 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1491 VAR=VALUE.  See below for descriptions of some of the useful variables.
1492
1493 Defaults for the options are specified in brackets.
1494
1495 Configuration:
1496   -h, --help              display this help and exit
1497       --help=short        display options specific to this package
1498       --help=recursive    display the short help of all the included packages
1499   -V, --version           display version information and exit
1500   -q, --quiet, --silent   do not print \`checking ...' messages
1501       --cache-file=FILE   cache test results in FILE [disabled]
1502   -C, --config-cache      alias for \`--cache-file=config.cache'
1503   -n, --no-create         do not create output files
1504       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1505
1506 Installation directories:
1507   --prefix=PREFIX         install architecture-independent files in PREFIX
1508                           [$ac_default_prefix]
1509   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1510                           [PREFIX]
1511
1512 By default, \`make install' will install all the files in
1513 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1514 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1515 for instance \`--prefix=\$HOME'.
1516
1517 For better control, use the options below.

1675   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1676               nonstandard directory <lib dir>
1677   LIBS        libraries to pass to the linker, e.g. -l<library>
1678   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1679               you have headers in a nonstandard directory <include dir>
1680   CXX         C++ compiler command
1681   CXXFLAGS    C++ compiler flags
1682   CPP         C preprocessor
1683   MAKEINFO    Parent configure detects if it is of sufficient version.
1684   MAKEINFOFLAGS
1685               Parameters for MAKEINFO.
1686   YACC        The `Yet Another Compiler Compiler' implementation to use.
1687               Defaults to the first program found out of: `bison -y', `byacc',
1688               `yacc'.
1689   YFLAGS      The list of arguments that will be passed by default to $YACC.
1690               This script will default YFLAGS to the empty string to avoid a
1691               default value of `-d' given by some make applications.
1692   XMKMF       Path to xmkmf, Makefile generator for X Window System
1693
1694 Use these variables to override the choices made by `configure' or to help
1695 it to find libraries and programs with nonstandard names/locations.

12827    Here is a matrix of mmap possibilities:
12828         mmap private not fixed
12829         mmap private fixed at somewhere currently unmapped
12830         mmap private fixed at somewhere already mapped
12831         mmap shared not fixed
12832         mmap shared fixed at somewhere currently unmapped
12833         mmap shared fixed at somewhere already mapped
12834    For private mappings, we should verify that changes cannot be read()
12835    back from the file, nor mmap's back from the file at a different
12836    address.  (There have been systems where private was not correctly
12837    implemented like the infamous i386 svr4.0, and systems where the
12838    VM page cache was not coherent with the file system buffer cache
12839    like early versions of FreeBSD and possibly contemporary NetBSD.)
12840    For shared mappings, we should conversely verify that changes get
12841    propagated back to all the places they're supposed to be.
12842
12843    Grep wants private fixed already mapped.
12844    The main things grep needs to know about mmap are:
12845    * does it exist and is it safe to write into the mmap'd area
12846    * how to use it (BSD variants)  */
