1482 \`configure' configures this package to adapt to many kinds of systems.
1483
1484 Usage: $0 [OPTION]... [VAR=VALUE]...
1485
1486 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1487 VAR=VALUE.  See below for descriptions of some of the useful variables.
1488
1489 Defaults for the options are specified in brackets.
1490
1491 Configuration:
1492   -h, --help              display this help and exit
1493       --help=short        display options specific to this package
1494       --help=recursive    display the short help of all the included packages
1495   -V, --version           display version information and exit
1496   -q, --quiet, --silent   do not print \`checking ...' messages
1497       --cache-file=FILE   cache test results in FILE [disabled]
1498   -C, --config-cache      alias for \`--cache-file=config.cache'
1499   -n, --no-create         do not create output files
1500       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1501
1502 Installation directories:
1503   --prefix=PREFIX         install architecture-independent files in PREFIX
1504                           [$ac_default_prefix]
1505   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1506                           [PREFIX]
1507
1508 By default, \`make install' will install all the files in
1509 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1510 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1511 for instance \`--prefix=\$HOME'.
1512
1513 For better control, use the options below.

1667 Some influential environment variables:
1668   CC          C compiler command

1670   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1671               nonstandard directory <lib dir>
1672   LIBS        libraries to pass to the linker, e.g. -l<library>
1673   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1674               you have headers in a nonstandard directory <include dir>
1675   CXX         C++ compiler command
1676   CXXFLAGS    C++ compiler flags
1677   CPP         C preprocessor
1678   MAKEINFO    Parent configure detects if it is of sufficient version.
1679   MAKEINFOFLAGS
1680               Parameters for MAKEINFO.
1681   YACC        The `Yet Another Compiler Compiler' implementation to use.
1682               Defaults to the first program found out of: `bison -y', `byacc',
1683               `yacc'.
1684   YFLAGS      The list of arguments that will be passed by default to $YACC.
1685               This script will default YFLAGS to the empty string to avoid a
1686               default value of `-d' given by some make applications.
1687   XMKMF       Path to xmkmf, Makefile generator for X Window System
1688
1689 Use these variables to override the choices made by `configure' or to help
1690 it to find libraries and programs with nonstandard names/locations.

12822    Here is a matrix of mmap possibilities:
12823         mmap private not fixed
12824         mmap private fixed at somewhere currently unmapped
12825         mmap private fixed at somewhere already mapped
12826         mmap shared not fixed
12827         mmap shared fixed at somewhere currently unmapped
12828         mmap shared fixed at somewhere already mapped
12829    For private mappings, we should verify that changes cannot be read()
12830    back from the file, nor mmap's back from the file at a different
12831    address.  (There have been systems where private was not correctly
12832    implemented like the infamous i386 svr4.0, and systems where the
12833    VM page cache was not coherent with the file system buffer cache
12834    like early versions of FreeBSD and possibly contemporary NetBSD.)
12835    For shared mappings, we should conversely verify that changes get
12836    propagated back to all the places they're supposed to be.
12837
12838    Grep wants private fixed already mapped.
12839    The main things grep needs to know about mmap are:
12840    * does it exist and is it safe to write into the mmap'd area
12841    * how to use it (BSD variants)  */
