2115 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2116
2117 Usage: $0 [OPTION]... [VAR=VALUE]...
2118
2119 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2120 VAR=VALUE.  See below for descriptions of some of the useful variables.
2121
2122 Defaults for the options are specified in brackets.
2123
2124 Configuration:
2125   -h, --help              display this help and exit
2126       --help=short        display options specific to this package
2127       --help=recursive    display the short help of all the included packages
2128   -V, --version           display version information and exit
2129   -q, --quiet, --silent   do not print \`checking...' messages
2130       --cache-file=FILE   cache test results in FILE [disabled]
2131   -C, --config-cache      alias for \`--cache-file=config.cache'
2132   -n, --no-create         do not create output files
2133       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2134
2135 Installation directories:
2136   --prefix=PREFIX         install architecture-independent files in PREFIX
2137                           [$ac_default_prefix]
2138   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2139                           [PREFIX]
2140
2141 By default, \`make install' will install all the files in
2142 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2143 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2144 for instance \`--prefix=\$HOME'.
2145
2146 For better control, use the options below.

2225                           tools.
2226   --enable-link-time-optimization
2227                           build emacs with link-time optimization. This is
2228                           supported only for GCC since 4.5.0.

10561    Here is a matrix of mmap possibilities:
10562         mmap private not fixed
10563         mmap private fixed at somewhere currently unmapped
10564         mmap private fixed at somewhere already mapped
10565         mmap shared not fixed
10566         mmap shared fixed at somewhere currently unmapped
10567         mmap shared fixed at somewhere already mapped
10568    For private mappings, we should verify that changes cannot be read()
10569    back from the file, nor mmap's back from the file at a different
10570    address.  (There have been systems where private was not correctly
10571    implemented like the infamous i386 svr4.0, and systems where the
10572    VM page cache was not coherent with the file system buffer cache
10573    like early versions of FreeBSD and possibly contemporary NetBSD.)
10574    For shared mappings, we should conversely verify that changes get
10575    propagated back to all the places they're supposed to be.
10576
10577    Grep wants private fixed already mapped.
10578    The main things grep needs to know about mmap are:
10579    * does it exist and is it safe to write into the mmap'd area
10580    * how to use it (BSD variants)  */
