1931 \`configure' configures emacs 24.1.50 to adapt to many kinds of systems.
1932
1933 Usage: $0 [OPTION]... [VAR=VALUE]...
1934
1935 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1936 VAR=VALUE.  See below for descriptions of some of the useful variables.
1937
1938 Defaults for the options are specified in brackets.
1939
1940 Configuration:
1941   -h, --help              display this help and exit
1942       --help=short        display options specific to this package
1943       --help=recursive    display the short help of all the included packages
1944   -V, --version           display version information and exit
1945   -q, --quiet, --silent   do not print \`checking...' messages
1946       --cache-file=FILE   cache test results in FILE [disabled]
1947   -C, --config-cache      alias for \`--cache-file=config.cache'
1948   -n, --no-create         do not create output files
1949       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1950
1951 Installation directories:
1952   --prefix=PREFIX         install architecture-independent files in PREFIX
1953                           [$ac_default_prefix]
1954   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1955                           [PREFIX]
1956
1957 By default, \`make install' will install all the files in
1958 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1959 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1960 for instance \`--prefix=\$HOME'.
1961
1962 For better control, use the options below.

2011   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2012   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
2013   --disable-ns-self-contained
2014                           disable self contained build under NeXTstep
2015   --enable-locallisppath=PATH
2016                           directories Emacs should search for lisp files
2017                           specific to this site
2018   --enable-checking[=LIST]
2019                           enable expensive run-time checks. With LIST, enable
2020                           only specific categories of checks. Categories are:
2021                           all,yes,no. Flags are: stringbytes, stringoverrun,
2022                           stringfreelist, xmallocoverrun, conslist, glyphs
2023   --enable-check-lisp-object-type
2024                           enable compile time checks for the Lisp_Object data
2025                           type. This is useful for development for catching
2026                           certain types of bugs.
2027   --enable-profiling      build emacs with profiling support. This might not
2028                           work on all platforms
2029   --enable-autodepend     automatically generate dependencies to .h-files.
2030                           Requires GNU Make and Gcc. Enabled if GNU Make and
2031                           Gcc is found
2032   --disable-dependency-tracking  speeds up one-time build
2033   --enable-dependency-tracking   do not reject slow dependency extractors
2034   --disable-largefile     omit support for large files
2035   --enable-gcc-warnings   turn on lots of GCC warnings. This is intended for
2036                           developers, and may generate false alarms when used
2037                           with older or non-GNU development tools.
2038   --enable-link-time-optimization
2039                           build emacs with link-time optimization. This is
2040                           supported only for GCC since 4.5.0.

17673    Here is a matrix of mmap possibilities:
17674         mmap private not fixed
17675         mmap private fixed at somewhere currently unmapped
17676         mmap private fixed at somewhere already mapped
17677         mmap shared not fixed
17678         mmap shared fixed at somewhere currently unmapped
17679         mmap shared fixed at somewhere already mapped
17680    For private mappings, we should verify that changes cannot be read()
17681    back from the file, nor mmap's back from the file at a different
17682    address.  (There have been systems where private was not correctly
17683    implemented like the infamous i386 svr4.0, and systems where the
17684    VM page cache was not coherent with the file system buffer cache
17685    like early versions of FreeBSD and possibly contemporary NetBSD.)
17686    For shared mappings, we should conversely verify that changes get
17687    propagated back to all the places they're supposed to be.
17688
17689    Grep wants private fixed already mapped.
17690    The main things grep needs to know about mmap are:
17691    * does it exist and is it safe to write into the mmap'd area
17692    * how to use it (BSD variants)  */
