2111 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2112
2113 Usage: $0 [OPTION]... [VAR=VALUE]...
2114
2115 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2116 VAR=VALUE.  See below for descriptions of some of the useful variables.
2117
2118 Defaults for the options are specified in brackets.
2119
2120 Configuration:
2121   -h, --help              display this help and exit
2122       --help=short        display options specific to this package
2123       --help=recursive    display the short help of all the included packages
2124   -V, --version           display version information and exit
2125   -q, --quiet, --silent   do not print \`checking...' messages
2126       --cache-file=FILE   cache test results in FILE [disabled]
2127   -C, --config-cache      alias for \`--cache-file=config.cache'
2128   -n, --no-create         do not create output files
2129       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2130
2131 Installation directories:
2132   --prefix=PREFIX         install architecture-independent files in PREFIX
2133                           [$ac_default_prefix]
2134   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2135                           [PREFIX]
2136
2137 By default, \`make install' will install all the files in
2138 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2139 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2140 for instance \`--prefix=\$HOME'.
2141
2142 For better control, use the options below.

2223                           build emacs with link-time optimization. This is
2224                           supported only for GCC since 4.5.0.

10546    Here is a matrix of mmap possibilities:
10547         mmap private not fixed
10548         mmap private fixed at somewhere currently unmapped
10549         mmap private fixed at somewhere already mapped
10550         mmap shared not fixed
10551         mmap shared fixed at somewhere currently unmapped
10552         mmap shared fixed at somewhere already mapped
10553    For private mappings, we should verify that changes cannot be read()
10554    back from the file, nor mmap's back from the file at a different
10555    address.  (There have been systems where private was not correctly
10556    implemented like the infamous i386 svr4.0, and systems where the
10557    VM page cache was not coherent with the file system buffer cache
10558    like early versions of FreeBSD and possibly contemporary NetBSD.)
10559    For shared mappings, we should conversely verify that changes get
10560    propagated back to all the places they're supposed to be.
10561
10562    Grep wants private fixed already mapped.
10563    The main things grep needs to know about mmap are:
10564    * does it exist and is it safe to write into the mmap'd area
10565    * how to use it (BSD variants)  */
