2072 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2073
2074 Usage: $0 [OPTION]... [VAR=VALUE]...
2075
2076 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2077 VAR=VALUE.  See below for descriptions of some of the useful variables.
2078
2079 Defaults for the options are specified in brackets.
2080
2081 Configuration:
2082   -h, --help              display this help and exit
2083       --help=short        display options specific to this package
2084       --help=recursive    display the short help of all the included packages
2085   -V, --version           display version information and exit
2086   -q, --quiet, --silent   do not print \`checking...' messages
2087       --cache-file=FILE   cache test results in FILE [disabled]
2088   -C, --config-cache      alias for \`--cache-file=config.cache'
2089   -n, --no-create         do not create output files
2090       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2091
2092 Installation directories:
2093   --prefix=PREFIX         install architecture-independent files in PREFIX
2094                           [$ac_default_prefix]
2095   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2096                           [PREFIX]
2097
2098 By default, \`make install' will install all the files in
2099 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2100 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2101 for instance \`--prefix=\$HOME'.
2102
2103 For better control, use the options below.

2160                           enable expensive run-time checks. With LIST, enable
2161                           only specific categories of checks. Categories are:
2162                           all,yes,no. Flags are: stringbytes, stringoverrun,
2163                           stringfreelist, xmallocoverrun, conslist, glyphs

2168   --enable-profiling      build emacs with low-level, gprof profiling support.
2169                           Mainly useful for debugging Emacs itself. May not
2170                           work on all platforms. Stops profiler.el working.

2180                           intended for developers, and may generate false
2181                           alarms when used with older or non-GNU development
2182                           tools.
2183   --enable-link-time-optimization
2184                           build emacs with link-time optimization. This is
2185                           supported only for GCC since 4.5.0.

10179    Here is a matrix of mmap possibilities:
10180         mmap private not fixed
10181         mmap private fixed at somewhere currently unmapped
10182         mmap private fixed at somewhere already mapped
10183         mmap shared not fixed
10184         mmap shared fixed at somewhere currently unmapped
10185         mmap shared fixed at somewhere already mapped
10186    For private mappings, we should verify that changes cannot be read()
10187    back from the file, nor mmap's back from the file at a different
10188    address.  (There have been systems where private was not correctly
10189    implemented like the infamous i386 svr4.0, and systems where the
10190    VM page cache was not coherent with the file system buffer cache
10191    like early versions of FreeBSD and possibly contemporary NetBSD.)
10192    For shared mappings, we should conversely verify that changes get
10193    propagated back to all the places they're supposed to be.
10194
10195    Grep wants private fixed already mapped.
10196    The main things grep needs to know about mmap are:
10197    * does it exist and is it safe to write into the mmap'd area
10198    * how to use it (BSD variants)  */
