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.

10519    Here is a matrix of mmap possibilities:
10520         mmap private not fixed
10521         mmap private fixed at somewhere currently unmapped
10522         mmap private fixed at somewhere already mapped
10523         mmap shared not fixed
10524         mmap shared fixed at somewhere currently unmapped
10525         mmap shared fixed at somewhere already mapped
10526    For private mappings, we should verify that changes cannot be read()
10527    back from the file, nor mmap's back from the file at a different
10528    address.  (There have been systems where private was not correctly
10529    implemented like the infamous i386 svr4.0, and systems where the
10530    VM page cache was not coherent with the file system buffer cache
10531    like early versions of FreeBSD and possibly contemporary NetBSD.)
10532    For shared mappings, we should conversely verify that changes get
10533    propagated back to all the places they're supposed to be.
10534
10535    Grep wants private fixed already mapped.
10536    The main things grep needs to know about mmap are:
10537    * does it exist and is it safe to write into the mmap'd area
10538    * how to use it (BSD variants)  */
