1459 \`configure' configures this package to adapt to many kinds of systems.
1460
1461 Usage: $0 [OPTION]... [VAR=VALUE]...
1462
1463 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1464 VAR=VALUE.  See below for descriptions of some of the useful variables.
1465
1466 Defaults for the options are specified in brackets.
1467
1468 Configuration:
1469   -h, --help              display this help and exit
1470       --help=short        display options specific to this package
1471       --help=recursive    display the short help of all the included packages
1472   -V, --version           display version information and exit
1473   -q, --quiet, --silent   do not print \`checking ...' messages
1474       --cache-file=FILE   cache test results in FILE [disabled]
1475   -C, --config-cache      alias for \`--cache-file=config.cache'
1476   -n, --no-create         do not create output files
1477       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1478
1479 Installation directories:
1480   --prefix=PREFIX         install architecture-independent files in PREFIX
1481                           [$ac_default_prefix]
1482   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1483                           [PREFIX]
1484
1485 By default, \`make install' will install all the files in
1486 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1487 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1488 for instance \`--prefix=\$HOME'.
1489
1490 For better control, use the options below.

1626 Some influential environment variables:
1627   CC          C compiler command
1628   CFLAGS      C compiler flags
1629   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1630               nonstandard directory <lib dir>
1631   LIBS        libraries to pass to the linker, e.g. -l<library>
1632   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1633               you have headers in a nonstandard directory <include dir>
1634   CXX         C++ compiler command
1635   CXXFLAGS    C++ compiler flags
1636   CPP         C preprocessor
1637   MAKEINFO    Parent configure detects if it is of sufficient version.
1638   MAKEINFOFLAGS
1639               Parameters for MAKEINFO.
1640   YACC        The `Yet Another Compiler Compiler' implementation to use.
1641               Defaults to the first program found out of: `bison -y', `byacc',
1642               `yacc'.
1643   YFLAGS      The list of arguments that will be passed by default to $YACC.
1644               This script will default YFLAGS to the empty string to avoid a
1645               default value of `-d' given by some make applications.
1646   XMKMF       Path to xmkmf, Makefile generator for X Window System
1647
1648 Use these variables to override the choices made by `configure' or to help
1649 it to find libraries and programs with nonstandard names/locations.

8849 #   defined to work on directories not files (though it really doesn't know
8850 #   the difference).
8851 # - Calling this --with-iconv-prefix is perceived to cause too much confusion

12939    Here is a matrix of mmap possibilities:
12940         mmap private not fixed
12941         mmap private fixed at somewhere currently unmapped
12942         mmap private fixed at somewhere already mapped
12943         mmap shared not fixed
12944         mmap shared fixed at somewhere currently unmapped
12945         mmap shared fixed at somewhere already mapped
12946    For private mappings, we should verify that changes cannot be read()
12947    back from the file, nor mmap's back from the file at a different
12948    address.  (There have been systems where private was not correctly
12949    implemented like the infamous i386 svr4.0, and systems where the
12950    VM page cache was not coherent with the file system buffer cache
12951    like early versions of FreeBSD and possibly contemporary NetBSD.)
12952    For shared mappings, we should conversely verify that changes get
12953    propagated back to all the places they're supposed to be.
12954
12955    Grep wants private fixed already mapped.
12956    The main things grep needs to know about mmap are:
12957    * does it exist and is it safe to write into the mmap'd area
12958    * how to use it (BSD variants)  */
