2107 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
2108
2109 Usage: $0 [OPTION]... [VAR=VALUE]...
2110
2111 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2112 VAR=VALUE.  See below for descriptions of some of the useful variables.
2113
2114 Defaults for the options are specified in brackets.
2115
2116 Configuration:
2117   -h, --help              display this help and exit
2118       --help=short        display options specific to this package
2119       --help=recursive    display the short help of all the included packages
2120   -V, --version           display version information and exit
2121   -q, --quiet, --silent   do not print \`checking...' messages
2122       --cache-file=FILE   cache test results in FILE [disabled]
2123   -C, --config-cache      alias for \`--cache-file=config.cache'
2124   -n, --no-create         do not create output files
2125       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2126
2127 Installation directories:
2128   --prefix=PREFIX         install architecture-independent files in PREFIX
2129                           [$ac_default_prefix]
2130   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2131                           [PREFIX]
2132
2133 By default, \`make install' will install all the files in
2134 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2135 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2136 for instance \`--prefix=\$HOME'.
2137
2138 For better control, use the options below.

2217                           tools.
2218   --enable-link-time-optimization
2219                           build emacs with link-time optimization. This is
2220                           supported only for GCC since 4.5.0.

10518    Here is a matrix of mmap possibilities:
10519         mmap private not fixed
10520         mmap private fixed at somewhere currently unmapped
10521         mmap private fixed at somewhere already mapped
10522         mmap shared not fixed
10523         mmap shared fixed at somewhere currently unmapped
10524         mmap shared fixed at somewhere already mapped
10525    For private mappings, we should verify that changes cannot be read()
10526    back from the file, nor mmap's back from the file at a different
10527    address.  (There have been systems where private was not correctly
10528    implemented like the infamous i386 svr4.0, and systems where the
10529    VM page cache was not coherent with the file system buffer cache
10530    like early versions of FreeBSD and possibly contemporary NetBSD.)
10531    For shared mappings, we should conversely verify that changes get
10532    propagated back to all the places they're supposed to be.
10533
10534    Grep wants private fixed already mapped.
10535    The main things grep needs to know about mmap are:
10536    * does it exist and is it safe to write into the mmap'd area
10537    * how to use it (BSD variants)  */
