1474 \`configure' configures this package to adapt to many kinds of systems.
1475
1476 Usage: $0 [OPTION]... [VAR=VALUE]...
1477
1478 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1479 VAR=VALUE.  See below for descriptions of some of the useful variables.
1480
1481 Defaults for the options are specified in brackets.
1482
1483 Configuration:
1484   -h, --help              display this help and exit
1485       --help=short        display options specific to this package
1486       --help=recursive    display the short help of all the included packages
1487   -V, --version           display version information and exit
1488   -q, --quiet, --silent   do not print \`checking ...' messages
1489       --cache-file=FILE   cache test results in FILE [disabled]
1490   -C, --config-cache      alias for \`--cache-file=config.cache'
1491   -n, --no-create         do not create output files
1492       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1493
1494 Installation directories:
1495   --prefix=PREFIX         install architecture-independent files in PREFIX
1496                           [$ac_default_prefix]
1497   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1498                           [PREFIX]
1499
1500 By default, \`make install' will install all the files in
1501 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1502 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1503 for instance \`--prefix=\$HOME'.
1504
1505 For better control, use the options below.

1650 Some influential environment variables:
1651   CC          C compiler command
1652   CFLAGS      C compiler flags
1653   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1654               nonstandard directory <lib dir>
1655   LIBS        libraries to pass to the linker, e.g. -l<library>
1656   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1657               you have headers in a nonstandard directory <include dir>
1658   CXX         C++ compiler command
1659   CXXFLAGS    C++ compiler flags
1660   CPP         C preprocessor
1661   MAKEINFO    Parent configure detects if it is of sufficient version.
1662   MAKEINFOFLAGS
1663               Parameters for MAKEINFO.
1664   YACC        The `Yet Another Compiler Compiler' implementation to use.
1665               Defaults to the first program found out of: `bison -y', `byacc',
1666               `yacc'.
1667   YFLAGS      The list of arguments that will be passed by default to $YACC.
1668               This script will default YFLAGS to the empty string to avoid a
1669               default value of `-d' given by some make applications.
1670   XMKMF       Path to xmkmf, Makefile generator for X Window System
1671
1672 Use these variables to override the choices made by `configure' or to help
1673 it to find libraries and programs with nonstandard names/locations.

8808 # - There is already --with-libiconv-prefix but we can't use it, it specifies
8809 #   the build-time location of libiconv files.
8810 # - The program we need to find is iconv, which comes with glibc.  The user
8811 #   doesn't necessarily have libiconv installed.  Therefore naming this
8812 #   --with-libiconv-foo feels wrong.
8813 # - We want the path to be relocatable, but GDB_AC_DEFINE_RELOCATABLE is
8814 #   defined to work on directories not files (though it really doesn't know
8815 #   the difference).
8816 # - Calling this --with-iconv-prefix is perceived to cause too much confusion
8817 #   with --with-libiconv-prefix.
8818 # Putting these together is why the option name is --with-iconv-bin.

12763    Here is a matrix of mmap possibilities:
12764         mmap private not fixed
12765         mmap private fixed at somewhere currently unmapped
12766         mmap private fixed at somewhere already mapped
12767         mmap shared not fixed
12768         mmap shared fixed at somewhere currently unmapped
12769         mmap shared fixed at somewhere already mapped
12770    For private mappings, we should verify that changes cannot be read()
12771    back from the file, nor mmap's back from the file at a different
12772    address.  (There have been systems where private was not correctly
12773    implemented like the infamous i386 svr4.0, and systems where the
12774    VM page cache was not coherent with the file system buffer cache
12775    like early versions of FreeBSD and possibly contemporary NetBSD.)
12776    For shared mappings, we should conversely verify that changes get
12777    propagated back to all the places they're supposed to be.
12778
12779    Grep wants private fixed already mapped.
12780    The main things grep needs to know about mmap are:
12781    * does it exist and is it safe to write into the mmap'd area
12782    * how to use it (BSD variants)  */
