1463 \`configure' configures this package to adapt to many kinds of systems.
1464
1465 Usage: $0 [OPTION]... [VAR=VALUE]...
1466
1467 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1468 VAR=VALUE.  See below for descriptions of some of the useful variables.
1469
1470 Defaults for the options are specified in brackets.
1471
1472 Configuration:
1473   -h, --help              display this help and exit
1474       --help=short        display options specific to this package
1475       --help=recursive    display the short help of all the included packages
1476   -V, --version           display version information and exit
1477   -q, --quiet, --silent   do not print \`checking ...' messages
1478       --cache-file=FILE   cache test results in FILE [disabled]
1479   -C, --config-cache      alias for \`--cache-file=config.cache'
1480   -n, --no-create         do not create output files
1481       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1482
1483 Installation directories:
1484   --prefix=PREFIX         install architecture-independent files in PREFIX
1485                           [$ac_default_prefix]
1486   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1487                           [PREFIX]
1488
1489 By default, \`make install' will install all the files in
1490 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1491 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1492 for instance \`--prefix=\$HOME'.
1493
1494 For better control, use the options below.

1634 Some influential environment variables:
1635   CC          C compiler command
1636   CFLAGS      C compiler flags
1637   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1638               nonstandard directory <lib dir>
1639   LIBS        libraries to pass to the linker, e.g. -l<library>
1640   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1641               you have headers in a nonstandard directory <include dir>
1642   CXX         C++ compiler command
1643   CXXFLAGS    C++ compiler flags
1644   CPP         C preprocessor
1645   MAKEINFO    Parent configure detects if it is of sufficient version.
1646   MAKEINFOFLAGS
1647               Parameters for MAKEINFO.
1648   YACC        The `Yet Another Compiler Compiler' implementation to use.
1649               Defaults to the first program found out of: `bison -y', `byacc',
1650               `yacc'.
1651   YFLAGS      The list of arguments that will be passed by default to $YACC.
1652               This script will default YFLAGS to the empty string to avoid a
1653               default value of `-d' given by some make applications.
1654   XMKMF       Path to xmkmf, Makefile generator for X Window System
1655
1656 Use these variables to override the choices made by `configure' or to help
1657 it to find libraries and programs with nonstandard names/locations.

12912    Here is a matrix of mmap possibilities:
12913         mmap private not fixed
12914         mmap private fixed at somewhere currently unmapped
12915         mmap private fixed at somewhere already mapped
12916         mmap shared not fixed
12917         mmap shared fixed at somewhere currently unmapped
12918         mmap shared fixed at somewhere already mapped
12919    For private mappings, we should verify that changes cannot be read()
12920    back from the file, nor mmap's back from the file at a different
12921    address.  (There have been systems where private was not correctly
12922    implemented like the infamous i386 svr4.0, and systems where the
12923    VM page cache was not coherent with the file system buffer cache
12924    like early versions of FreeBSD and possibly contemporary NetBSD.)
12925    For shared mappings, we should conversely verify that changes get
12926    propagated back to all the places they're supposed to be.
12927
12928    Grep wants private fixed already mapped.
12929    The main things grep needs to know about mmap are:
12930    * does it exist and is it safe to write into the mmap'd area
12931    * how to use it (BSD variants)  */
