1460 \`configure' configures this package to adapt to many kinds of systems.
1461
1462 Usage: $0 [OPTION]... [VAR=VALUE]...
1463
1464 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1465 VAR=VALUE.  See below for descriptions of some of the useful variables.
1466
1467 Defaults for the options are specified in brackets.
1468
1469 Configuration:
1470   -h, --help              display this help and exit
1471       --help=short        display options specific to this package
1472       --help=recursive    display the short help of all the included packages
1473   -V, --version           display version information and exit
1474   -q, --quiet, --silent   do not print \`checking ...' messages
1475       --cache-file=FILE   cache test results in FILE [disabled]
1476   -C, --config-cache      alias for \`--cache-file=config.cache'
1477   -n, --no-create         do not create output files
1478       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1479
1480 Installation directories:
1481   --prefix=PREFIX         install architecture-independent files in PREFIX
1482                           [$ac_default_prefix]
1483   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1484                           [PREFIX]
1485
1486 By default, \`make install' will install all the files in
1487 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1488 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1489 for instance \`--prefix=\$HOME'.
1490
1491 For better control, use the options below.

1627 Some influential environment variables:
1628   CC          C compiler command
1629   CFLAGS      C compiler flags
1630   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1631               nonstandard directory <lib dir>
1632   LIBS        libraries to pass to the linker, e.g. -l<library>
1633   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1634               you have headers in a nonstandard directory <include dir>
1635   CXX         C++ compiler command
1636   CXXFLAGS    C++ compiler flags
1637   CPP         C preprocessor
1638   MAKEINFO    Parent configure detects if it is of sufficient version.
1639   MAKEINFOFLAGS
1640               Parameters for MAKEINFO.
1641   YACC        The `Yet Another Compiler Compiler' implementation to use.
1642               Defaults to the first program found out of: `bison -y', `byacc',
1643               `yacc'.
1644   YFLAGS      The list of arguments that will be passed by default to $YACC.
1645               This script will default YFLAGS to the empty string to avoid a
1646               default value of `-d' given by some make applications.
1647   XMKMF       Path to xmkmf, Makefile generator for X Window System
1648
1649 Use these variables to override the choices made by `configure' or to help
1650 it to find libraries and programs with nonstandard names/locations.

12920    Here is a matrix of mmap possibilities:
12921         mmap private not fixed
12922         mmap private fixed at somewhere currently unmapped
12923         mmap private fixed at somewhere already mapped
12924         mmap shared not fixed
12925         mmap shared fixed at somewhere currently unmapped
12926         mmap shared fixed at somewhere already mapped
12927    For private mappings, we should verify that changes cannot be read()
12928    back from the file, nor mmap's back from the file at a different
12929    address.  (There have been systems where private was not correctly
12930    implemented like the infamous i386 svr4.0, and systems where the
12931    VM page cache was not coherent with the file system buffer cache
12932    like early versions of FreeBSD and possibly contemporary NetBSD.)
12933    For shared mappings, we should conversely verify that changes get
12934    propagated back to all the places they're supposed to be.
12935
12936    Grep wants private fixed already mapped.
12937    The main things grep needs to know about mmap are:
12938    * does it exist and is it safe to write into the mmap'd area
12939    * how to use it (BSD variants)  */
