1939 \`configure' configures emacs 24.2.50 to adapt to many kinds of systems.
1940
1941 Usage: $0 [OPTION]... [VAR=VALUE]...
1942
1943 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1944 VAR=VALUE.  See below for descriptions of some of the useful variables.
1945
1946 Defaults for the options are specified in brackets.
1947
1948 Configuration:
1949   -h, --help              display this help and exit
1950       --help=short        display options specific to this package
1951       --help=recursive    display the short help of all the included packages
1952   -V, --version           display version information and exit
1953   -q, --quiet, --silent   do not print \`checking...' messages
1954       --cache-file=FILE   cache test results in FILE [disabled]
1955   -C, --config-cache      alias for \`--cache-file=config.cache'
1956   -n, --no-create         do not create output files
1957       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1958
1959 Installation directories:
1960   --prefix=PREFIX         install architecture-independent files in PREFIX
1961                           [$ac_default_prefix]
1962   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1963                           [PREFIX]
1964
1965 By default, \`make install' will install all the files in
1966 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1967 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1968 for instance \`--prefix=\$HOME'.
1969
1970 For better control, use the options below.

2028                           only specific categories of checks. Categories are:
2029                           all,yes,no. Flags are: stringbytes, stringoverrun,
2030                           stringfreelist, xmallocoverrun, conslist, glyphs

2043   --enable-gcc-warnings   turn on lots of GCC warnings. This is intended for
2044                           developers, and may generate false alarms when used
2045                           with older or non-GNU development tools.
2046   --enable-link-time-optimization
2047                           build emacs with link-time optimization. This is
2048                           supported only for GCC since 4.5.0.

9767    Here is a matrix of mmap possibilities:
9768         mmap private not fixed
9769         mmap private fixed at somewhere currently unmapped
9770         mmap private fixed at somewhere already mapped
9771         mmap shared not fixed
9772         mmap shared fixed at somewhere currently unmapped
9773         mmap shared fixed at somewhere already mapped
9774    For private mappings, we should verify that changes cannot be read()
9775    back from the file, nor mmap's back from the file at a different
9776    address.  (There have been systems where private was not correctly
9777    implemented like the infamous i386 svr4.0, and systems where the
9778    VM page cache was not coherent with the file system buffer cache
9779    like early versions of FreeBSD and possibly contemporary NetBSD.)
9780    For shared mappings, we should conversely verify that changes get
9781    propagated back to all the places they're supposed to be.
9782
9783    Grep wants private fixed already mapped.
9784    The main things grep needs to know about mmap are:
9785    * does it exist and is it safe to write into the mmap'd area
9786    * how to use it (BSD variants)  */
