1461 \`configure' configures this package to adapt to many kinds of systems.
1462
1463 Usage: $0 [OPTION]... [VAR=VALUE]...
1464
1465 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1466 VAR=VALUE.  See below for descriptions of some of the useful variables.
1467
1468 Defaults for the options are specified in brackets.
1469
1470 Configuration:
1471   -h, --help              display this help and exit
1472       --help=short        display options specific to this package
1473       --help=recursive    display the short help of all the included packages
1474   -V, --version           display version information and exit
1475   -q, --quiet, --silent   do not print \`checking ...' messages
1476       --cache-file=FILE   cache test results in FILE [disabled]
1477   -C, --config-cache      alias for \`--cache-file=config.cache'
1478   -n, --no-create         do not create output files
1479       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1480
1481 Installation directories:
1482   --prefix=PREFIX         install architecture-independent files in PREFIX
1483                           [$ac_default_prefix]
1484   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1485                           [PREFIX]
1486
1487 By default, \`make install' will install all the files in
1488 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1489 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1490 for instance \`--prefix=\$HOME'.
1491
1492 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.

12745    Here is a matrix of mmap possibilities:
12746         mmap private not fixed
12747         mmap private fixed at somewhere currently unmapped
12748         mmap private fixed at somewhere already mapped
12749         mmap shared not fixed
12750         mmap shared fixed at somewhere currently unmapped
12751         mmap shared fixed at somewhere already mapped
12752    For private mappings, we should verify that changes cannot be read()
12753    back from the file, nor mmap's back from the file at a different
12754    address.  (There have been systems where private was not correctly
12755    implemented like the infamous i386 svr4.0, and systems where the
12756    VM page cache was not coherent with the file system buffer cache
12757    like early versions of FreeBSD and possibly contemporary NetBSD.)
12758    For shared mappings, we should conversely verify that changes get
12759    propagated back to all the places they're supposed to be.
12760
12761    Grep wants private fixed already mapped.
12762    The main things grep needs to know about mmap are:
12763    * does it exist and is it safe to write into the mmap'd area
12764    * how to use it (BSD variants)  */
