2077 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2078
2079 Usage: $0 [OPTION]... [VAR=VALUE]...
2080
2081 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2082 VAR=VALUE.  See below for descriptions of some of the useful variables.
2083
2084 Defaults for the options are specified in brackets.
2085
2086 Configuration:
2087   -h, --help              display this help and exit
2088       --help=short        display options specific to this package
2089       --help=recursive    display the short help of all the included packages
2090   -V, --version           display version information and exit
2091   -q, --quiet, --silent   do not print \`checking...' messages
2092       --cache-file=FILE   cache test results in FILE [disabled]
2093   -C, --config-cache      alias for \`--cache-file=config.cache'
2094   -n, --no-create         do not create output files
2095       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2096
2097 Installation directories:
2098   --prefix=PREFIX         install architecture-independent files in PREFIX
2099                           [$ac_default_prefix]
2100   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2101                           [PREFIX]
2102
2103 By default, \`make install' will install all the files in
2104 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2105 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2106 for instance \`--prefix=\$HOME'.
2107
2108 For better control, use the options below.

2173   --enable-profiling      build emacs with low-level, gprof profiling support.
2174                           Mainly useful for debugging Emacs itself. May not

2187                           tools.
2188   --enable-link-time-optimization
2189                           build emacs with link-time optimization. This is
2190                           supported only for GCC since 4.5.0.

10216    Here is a matrix of mmap possibilities:
10217         mmap private not fixed
10218         mmap private fixed at somewhere currently unmapped
10219         mmap private fixed at somewhere already mapped
10220         mmap shared not fixed
10221         mmap shared fixed at somewhere currently unmapped
10222         mmap shared fixed at somewhere already mapped
10223    For private mappings, we should verify that changes cannot be read()
10224    back from the file, nor mmap's back from the file at a different
10225    address.  (There have been systems where private was not correctly
10226    implemented like the infamous i386 svr4.0, and systems where the
10227    VM page cache was not coherent with the file system buffer cache
10228    like early versions of FreeBSD and possibly contemporary NetBSD.)
10229    For shared mappings, we should conversely verify that changes get
10230    propagated back to all the places they're supposed to be.
10231
10232    Grep wants private fixed already mapped.
10233    The main things grep needs to know about mmap are:
10234    * does it exist and is it safe to write into the mmap'd area
10235    * how to use it (BSD variants)  */
