1462 \`configure' configures this package to adapt to many kinds of systems.
1463
1464 Usage: $0 [OPTION]... [VAR=VALUE]...
1465
1466 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1467 VAR=VALUE.  See below for descriptions of some of the useful variables.
1468
1469 Defaults for the options are specified in brackets.
1470
1471 Configuration:
1472   -h, --help              display this help and exit
1473       --help=short        display options specific to this package
1474       --help=recursive    display the short help of all the included packages
1475   -V, --version           display version information and exit
1476   -q, --quiet, --silent   do not print \`checking ...' messages
1477       --cache-file=FILE   cache test results in FILE [disabled]
1478   -C, --config-cache      alias for \`--cache-file=config.cache'
1479   -n, --no-create         do not create output files
1480       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1481
1482 Installation directories:
1483   --prefix=PREFIX         install architecture-independent files in PREFIX
1484                           [$ac_default_prefix]
1485   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1486                           [PREFIX]
1487
1488 By default, \`make install' will install all the files in
1489 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1490 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1491 for instance \`--prefix=\$HOME'.
1492
1493 For better control, use the options below.

1631 Some influential environment variables:
1632   CC          C compiler command
1633   CFLAGS      C compiler flags
1634   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1635               nonstandard directory <lib dir>
1636   LIBS        libraries to pass to the linker, e.g. -l<library>
1637   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1638               you have headers in a nonstandard directory <include dir>
1639   CXX         C++ compiler command
1640   CXXFLAGS    C++ compiler flags
1641   CPP         C preprocessor
1642   MAKEINFO    Parent configure detects if it is of sufficient version.
1643   MAKEINFOFLAGS
1644               Parameters for MAKEINFO.
1645   YACC        The `Yet Another Compiler Compiler' implementation to use.
1646               Defaults to the first program found out of: `bison -y', `byacc',
1647               `yacc'.
1648   YFLAGS      The list of arguments that will be passed by default to $YACC.
1649               This script will default YFLAGS to the empty string to avoid a
1650               default value of `-d' given by some make applications.
1651   XMKMF       Path to xmkmf, Makefile generator for X Window System
1652
1653 Use these variables to override the choices made by `configure' or to help
1654 it to find libraries and programs with nonstandard names/locations.

12888    Here is a matrix of mmap possibilities:
12889         mmap private not fixed
12890         mmap private fixed at somewhere currently unmapped
12891         mmap private fixed at somewhere already mapped
12892         mmap shared not fixed
12893         mmap shared fixed at somewhere currently unmapped
12894         mmap shared fixed at somewhere already mapped
12895    For private mappings, we should verify that changes cannot be read()
12896    back from the file, nor mmap's back from the file at a different
12897    address.  (There have been systems where private was not correctly
12898    implemented like the infamous i386 svr4.0, and systems where the
12899    VM page cache was not coherent with the file system buffer cache
12900    like early versions of FreeBSD and possibly contemporary NetBSD.)
12901    For shared mappings, we should conversely verify that changes get
12902    propagated back to all the places they're supposed to be.
12903
12904    Grep wants private fixed already mapped.
12905    The main things grep needs to know about mmap are:
12906    * does it exist and is it safe to write into the mmap'd area
12907    * how to use it (BSD variants)  */
