1943 \`configure' configures emacs 24.3 to adapt to many kinds of systems.
1944
1945 Usage: $0 [OPTION]... [VAR=VALUE]...
1946
1947 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1948 VAR=VALUE.  See below for descriptions of some of the useful variables.
1949
1950 Defaults for the options are specified in brackets.
1951
1952 Configuration:
1953   -h, --help              display this help and exit
1954       --help=short        display options specific to this package
1955       --help=recursive    display the short help of all the included packages
1956   -V, --version           display version information and exit
1957   -q, --quiet, --silent   do not print \`checking...' messages
1958       --cache-file=FILE   cache test results in FILE [disabled]
1959   -C, --config-cache      alias for \`--cache-file=config.cache'
1960   -n, --no-create         do not create output files
1961       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1962
1963 Installation directories:
1964   --prefix=PREFIX         install architecture-independent files in PREFIX
1965                           [$ac_default_prefix]
1966   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1967                           [PREFIX]
1968
1969 By default, \`make install' will install all the files in
1970 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1971 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1972 for instance \`--prefix=\$HOME'.
1973
1974 For better control, use the options below.

1977   --bindir=DIR            user executables [EPREFIX/bin]

2021 Optional Features:
2022   --disable-option-checking  ignore unrecognized --enable/--with options
2023   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2024   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
2025   --disable-ns-self-contained
2026                           disable self contained build under NeXTstep
2027   --enable-locallisppath=PATH
2028                           directories Emacs should search for lisp files
2029                           specific to this site
2030   --enable-checking[=LIST]
2031                           enable expensive run-time checks. With LIST, enable
2032                           only specific categories of checks. Categories are:
2033                           all,yes,no. Flags are: stringbytes, stringoverrun,
2034                           stringfreelist, xmallocoverrun, conslist, glyphs
2035   --enable-check-lisp-object-type
2036                           enable compile time checks for the Lisp_Object data
2037                           type. This is useful for development for catching
2038                           certain types of bugs.
2039   --enable-profiling      build emacs with low-level, gprof profiling support.
2040                           Mainly useful for debugging Emacs itself. May not
2041                           work on all platforms. Stops profiler.el working.
2042   --enable-autodepend     automatically generate dependencies to .h-files.
2043                           Requires GNU Make and Gcc. Enabled if GNU Make and
2044                           Gcc is found
2045   --disable-dependency-tracking  speeds up one-time build
2046   --enable-dependency-tracking   do not reject slow dependency extractors
2047   --disable-largefile     omit support for large files
2048   --enable-gcc-warnings   turn on lots of GCC warnings/errors. This is
2049                           intended for developers, and may generate false
2050                           alarms when used with older or non-GNU development
2051                           tools.
2052   --enable-link-time-optimization
2053                           build emacs with link-time optimization. This is
2054                           supported only for GCC since 4.5.0.

9867    Here is a matrix of mmap possibilities:
9868         mmap private not fixed
9869         mmap private fixed at somewhere currently unmapped
9870         mmap private fixed at somewhere already mapped
9871         mmap shared not fixed
9872         mmap shared fixed at somewhere currently unmapped
9873         mmap shared fixed at somewhere already mapped
9874    For private mappings, we should verify that changes cannot be read()
9875    back from the file, nor mmap's back from the file at a different
9876    address.  (There have been systems where private was not correctly
9877    implemented like the infamous i386 svr4.0, and systems where the
9878    VM page cache was not coherent with the file system buffer cache
9879    like early versions of FreeBSD and possibly contemporary NetBSD.)
9880    For shared mappings, we should conversely verify that changes get
9881    propagated back to all the places they're supposed to be.
9882
9883    Grep wants private fixed already mapped.
9884    The main things grep needs to know about mmap are:
9885    * does it exist and is it safe to write into the mmap'd area
9886    * how to use it (BSD variants)  */
