2120 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2121
2122 Usage: $0 [OPTION]... [VAR=VALUE]...
2123
2124 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2125 VAR=VALUE.  See below for descriptions of some of the useful variables.
2126
2127 Defaults for the options are specified in brackets.
2128
2129 Configuration:
2130   -h, --help              display this help and exit
2131       --help=short        display options specific to this package
2132       --help=recursive    display the short help of all the included packages
2133   -V, --version           display version information and exit
2134   -q, --quiet, --silent   do not print \`checking...' messages
2135       --cache-file=FILE   cache test results in FILE [disabled]
2136   -C, --config-cache      alias for \`--cache-file=config.cache'
2137   -n, --no-create         do not create output files
2138       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2139
2140 Installation directories:
2141   --prefix=PREFIX         install architecture-independent files in PREFIX
2142                           [$ac_default_prefix]
2143   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2144                           [PREFIX]
2145
2146 By default, \`make install' will install all the files in
2147 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2148 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2149 for instance \`--prefix=\$HOME'.
2150
2151 For better control, use the options below.

2230                           tools.

2232                           build emacs with link-time optimization. This is
2233                           supported only for GCC since 4.5.0.

10856    Here is a matrix of mmap possibilities:
10857         mmap private not fixed
10858         mmap private fixed at somewhere currently unmapped
10859         mmap private fixed at somewhere already mapped
10860         mmap shared not fixed
10861         mmap shared fixed at somewhere currently unmapped
10862         mmap shared fixed at somewhere already mapped
10863    For private mappings, we should verify that changes cannot be read()
10864    back from the file, nor mmap's back from the file at a different
10865    address.  (There have been systems where private was not correctly
10866    implemented like the infamous i386 svr4.0, and systems where the
10867    VM page cache was not coherent with the file system buffer cache
10868    like early versions of FreeBSD and possibly contemporary NetBSD.)
10869    For shared mappings, we should conversely verify that changes get
10870    propagated back to all the places they're supposed to be.
10871
10872    Grep wants private fixed already mapped.
10873    The main things grep needs to know about mmap are:
10874    * does it exist and is it safe to write into the mmap'd area
10875    * how to use it (BSD variants)  */
