2117 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2118
2119 Usage: $0 [OPTION]... [VAR=VALUE]...
2120
2121 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2122 VAR=VALUE.  See below for descriptions of some of the useful variables.
2123
2124 Defaults for the options are specified in brackets.
2125
2126 Configuration:
2127   -h, --help              display this help and exit
2128       --help=short        display options specific to this package
2129       --help=recursive    display the short help of all the included packages
2130   -V, --version           display version information and exit
2131   -q, --quiet, --silent   do not print \`checking...' messages
2132       --cache-file=FILE   cache test results in FILE [disabled]
2133   -C, --config-cache      alias for \`--cache-file=config.cache'
2134   -n, --no-create         do not create output files
2135       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2136
2137 Installation directories:
2138   --prefix=PREFIX         install architecture-independent files in PREFIX
2139                           [$ac_default_prefix]
2140   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2141                           [PREFIX]
2142
2143 By default, \`make install' will install all the files in
2144 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2145 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2146 for instance \`--prefix=\$HOME'.
2147
2148 For better control, use the options below.

2227                           tools.

2229                           build emacs with link-time optimization. This is
2230                           supported only for GCC since 4.5.0.

10598    Here is a matrix of mmap possibilities:
10599         mmap private not fixed
10600         mmap private fixed at somewhere currently unmapped
10601         mmap private fixed at somewhere already mapped
10602         mmap shared not fixed
10603         mmap shared fixed at somewhere currently unmapped
10604         mmap shared fixed at somewhere already mapped
10605    For private mappings, we should verify that changes cannot be read()
10606    back from the file, nor mmap's back from the file at a different
10607    address.  (There have been systems where private was not correctly
10608    implemented like the infamous i386 svr4.0, and systems where the
10609    VM page cache was not coherent with the file system buffer cache
10610    like early versions of FreeBSD and possibly contemporary NetBSD.)
10611    For shared mappings, we should conversely verify that changes get
10612    propagated back to all the places they're supposed to be.
10613
10614    Grep wants private fixed already mapped.
10615    The main things grep needs to know about mmap are:
10616    * does it exist and is it safe to write into the mmap'd area
10617    * how to use it (BSD variants)  */
