1936 \`configure' configures emacs 24.2.50 to adapt to many kinds of systems.
1937
1938 Usage: $0 [OPTION]... [VAR=VALUE]...
1939
1940 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1941 VAR=VALUE.  See below for descriptions of some of the useful variables.
1942
1943 Defaults for the options are specified in brackets.
1944
1945 Configuration:
1946   -h, --help              display this help and exit
1947       --help=short        display options specific to this package
1948       --help=recursive    display the short help of all the included packages
1949   -V, --version           display version information and exit
1950   -q, --quiet, --silent   do not print \`checking...' messages
1951       --cache-file=FILE   cache test results in FILE [disabled]
1952   -C, --config-cache      alias for \`--cache-file=config.cache'
1953   -n, --no-create         do not create output files
1954       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1955
1956 Installation directories:
1957   --prefix=PREFIX         install architecture-independent files in PREFIX
1958                           [$ac_default_prefix]
1959   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1960                           [PREFIX]
1961
1962 By default, \`make install' will install all the files in
1963 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1964 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1965 for instance \`--prefix=\$HOME'.
1966
1967 For better control, use the options below.

9750    Here is a matrix of mmap possibilities:
9751         mmap private not fixed
9752         mmap private fixed at somewhere currently unmapped
9753         mmap private fixed at somewhere already mapped
9754         mmap shared not fixed
9755         mmap shared fixed at somewhere currently unmapped
9756         mmap shared fixed at somewhere already mapped
9757    For private mappings, we should verify that changes cannot be read()
9758    back from the file, nor mmap's back from the file at a different
9759    address.  (There have been systems where private was not correctly
9760    implemented like the infamous i386 svr4.0, and systems where the
9761    VM page cache was not coherent with the file system buffer cache
9762    like early versions of FreeBSD and possibly contemporary NetBSD.)
9763    For shared mappings, we should conversely verify that changes get
9764    propagated back to all the places they're supposed to be.
9765
9766    Grep wants private fixed already mapped.
9767    The main things grep needs to know about mmap are:
9768    * does it exist and is it safe to write into the mmap'd area
9769    * how to use it (BSD variants)  */
