2121 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2122
2123 Usage: $0 [OPTION]... [VAR=VALUE]...
2124
2125 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2126 VAR=VALUE.  See below for descriptions of some of the useful variables.
2127
2128 Defaults for the options are specified in brackets.
2129
2130 Configuration:
2131   -h, --help              display this help and exit
2132       --help=short        display options specific to this package
2133       --help=recursive    display the short help of all the included packages
2134   -V, --version           display version information and exit
2135   -q, --quiet, --silent   do not print \`checking...' messages
2136       --cache-file=FILE   cache test results in FILE [disabled]
2137   -C, --config-cache      alias for \`--cache-file=config.cache'
2138   -n, --no-create         do not create output files
2139       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2140
2141 Installation directories:
2142   --prefix=PREFIX         install architecture-independent files in PREFIX
2143                           [$ac_default_prefix]
2144   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2145                           [PREFIX]
2146
2147 By default, \`make install' will install all the files in
2148 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2149 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2150 for instance \`--prefix=\$HOME'.
2151
2152 For better control, use the options below.

2231                           tools.
2232   --enable-link-time-optimization
2233                           build emacs with link-time optimization. This is
2234                           supported only for GCC since 4.5.0.

10844    Here is a matrix of mmap possibilities:
10845         mmap private not fixed
10846         mmap private fixed at somewhere currently unmapped
10847         mmap private fixed at somewhere already mapped
10848         mmap shared not fixed
10849         mmap shared fixed at somewhere currently unmapped
10850         mmap shared fixed at somewhere already mapped
10851    For private mappings, we should verify that changes cannot be read()
10852    back from the file, nor mmap's back from the file at a different
10853    address.  (There have been systems where private was not correctly
10854    implemented like the infamous i386 svr4.0, and systems where the
10855    VM page cache was not coherent with the file system buffer cache
10856    like early versions of FreeBSD and possibly contemporary NetBSD.)
10857    For shared mappings, we should conversely verify that changes get
10858    propagated back to all the places they're supposed to be.
10859
10860    Grep wants private fixed already mapped.
10861    The main things grep needs to know about mmap are:
10862    * does it exist and is it safe to write into the mmap'd area
10863    * how to use it (BSD variants)  */
