1472 \`configure' configures this package to adapt to many kinds of systems.
1473
1474 Usage: $0 [OPTION]... [VAR=VALUE]...
1475
1476 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1477 VAR=VALUE.  See below for descriptions of some of the useful variables.
1478
1479 Defaults for the options are specified in brackets.
1480
1481 Configuration:
1482   -h, --help              display this help and exit
1483       --help=short        display options specific to this package
1484       --help=recursive    display the short help of all the included packages
1485   -V, --version           display version information and exit
1486   -q, --quiet, --silent   do not print \`checking ...' messages
1487       --cache-file=FILE   cache test results in FILE [disabled]
1488   -C, --config-cache      alias for \`--cache-file=config.cache'
1489   -n, --no-create         do not create output files
1490       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1491
1492 Installation directories:
1493   --prefix=PREFIX         install architecture-independent files in PREFIX
1494                           [$ac_default_prefix]
1495   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1496                           [PREFIX]
1497
1498 By default, \`make install' will install all the files in
1499 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1500 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1501 for instance \`--prefix=\$HOME'.
1502
1503 For better control, use the options below.

1646 Some influential environment variables:
1647   CC          C compiler command
1648   CFLAGS      C compiler flags
1649   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1650               nonstandard directory <lib dir>
1651   LIBS        libraries to pass to the linker, e.g. -l<library>
1652   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1653               you have headers in a nonstandard directory <include dir>
1654   CXX         C++ compiler command
1655   CXXFLAGS    C++ compiler flags
1656   CPP         C preprocessor
1657   MAKEINFO    Parent configure detects if it is of sufficient version.
1658   MAKEINFOFLAGS
1659               Parameters for MAKEINFO.
1660   YACC        The `Yet Another Compiler Compiler' implementation to use.
1661               Defaults to the first program found out of: `bison -y', `byacc',
1662               `yacc'.
1663   YFLAGS      The list of arguments that will be passed by default to $YACC.
1664               This script will default YFLAGS to the empty string to avoid a
1665               default value of `-d' given by some make applications.
1666   XMKMF       Path to xmkmf, Makefile generator for X Window System
1667
1668 Use these variables to override the choices made by `configure' or to help
1669 it to find libraries and programs with nonstandard names/locations.

12626    Here is a matrix of mmap possibilities:
12627         mmap private not fixed
12628         mmap private fixed at somewhere currently unmapped
12629         mmap private fixed at somewhere already mapped
12630         mmap shared not fixed
12631         mmap shared fixed at somewhere currently unmapped
12632         mmap shared fixed at somewhere already mapped
12633    For private mappings, we should verify that changes cannot be read()
12634    back from the file, nor mmap's back from the file at a different
12635    address.  (There have been systems where private was not correctly
12636    implemented like the infamous i386 svr4.0, and systems where the
12637    VM page cache was not coherent with the file system buffer cache
12638    like early versions of FreeBSD and possibly contemporary NetBSD.)
12639    For shared mappings, we should conversely verify that changes get
12640    propagated back to all the places they're supposed to be.
12641
12642    Grep wants private fixed already mapped.
12643    The main things grep needs to know about mmap are:
12644    * does it exist and is it safe to write into the mmap'd area
12645    * how to use it (BSD variants)  */
