1467 \`configure' configures this package to adapt to many kinds of systems.
1468
1469 Usage: $0 [OPTION]... [VAR=VALUE]...
1470
1471 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1472 VAR=VALUE.  See below for descriptions of some of the useful variables.
1473
1474 Defaults for the options are specified in brackets.
1475
1476 Configuration:
1477   -h, --help              display this help and exit
1478       --help=short        display options specific to this package
1479       --help=recursive    display the short help of all the included packages
1480   -V, --version           display version information and exit
1481   -q, --quiet, --silent   do not print \`checking ...' messages
1482       --cache-file=FILE   cache test results in FILE [disabled]
1483   -C, --config-cache      alias for \`--cache-file=config.cache'
1484   -n, --no-create         do not create output files
1485       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1486
1487 Installation directories:
1488   --prefix=PREFIX         install architecture-independent files in PREFIX
1489                           [$ac_default_prefix]
1490   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1491                           [PREFIX]
1492
1493 By default, \`make install' will install all the files in
1494 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1495 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1496 for instance \`--prefix=\$HOME'.
1497
1498 For better control, use the options below.

1640 Some influential environment variables:
1641   CC          C compiler command
1642   CFLAGS      C compiler flags
1643   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1644               nonstandard directory <lib dir>
1645   LIBS        libraries to pass to the linker, e.g. -l<library>
1646   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1647               you have headers in a nonstandard directory <include dir>
1648   CXX         C++ compiler command
1649   CXXFLAGS    C++ compiler flags
1650   CPP         C preprocessor
1651   MAKEINFO    Parent configure detects if it is of sufficient version.
1652   MAKEINFOFLAGS
1653               Parameters for MAKEINFO.
1654   YACC        The `Yet Another Compiler Compiler' implementation to use.
1655               Defaults to the first program found out of: `bison -y', `byacc',
1656               `yacc'.
1657   YFLAGS      The list of arguments that will be passed by default to $YACC.
1658               This script will default YFLAGS to the empty string to avoid a
1659               default value of `-d' given by some make applications.
1660   XMKMF       Path to xmkmf, Makefile generator for X Window System
1661
1662 Use these variables to override the choices made by `configure' or to help
1663 it to find libraries and programs with nonstandard names/locations.

12718    Here is a matrix of mmap possibilities:
12719         mmap private not fixed
12720         mmap private fixed at somewhere currently unmapped
12721         mmap private fixed at somewhere already mapped
12722         mmap shared not fixed
12723         mmap shared fixed at somewhere currently unmapped
12724         mmap shared fixed at somewhere already mapped
12725    For private mappings, we should verify that changes cannot be read()
12726    back from the file, nor mmap's back from the file at a different
12727    address.  (There have been systems where private was not correctly
12728    implemented like the infamous i386 svr4.0, and systems where the
12729    VM page cache was not coherent with the file system buffer cache
12730    like early versions of FreeBSD and possibly contemporary NetBSD.)
12731    For shared mappings, we should conversely verify that changes get
12732    propagated back to all the places they're supposed to be.
12733
12734    Grep wants private fixed already mapped.
12735    The main things grep needs to know about mmap are:
12736    * does it exist and is it safe to write into the mmap'd area
12737    * how to use it (BSD variants)  */
