1930 \`configure' configures emacs 24.1.50 to adapt to many kinds of systems.
1931
1932 Usage: $0 [OPTION]... [VAR=VALUE]...
1933
1934 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1935 VAR=VALUE.  See below for descriptions of some of the useful variables.
1936
1937 Defaults for the options are specified in brackets.
1938
1939 Configuration:
1940   -h, --help              display this help and exit
1941       --help=short        display options specific to this package
1942       --help=recursive    display the short help of all the included packages
1943   -V, --version           display version information and exit
1944   -q, --quiet, --silent   do not print \`checking...' messages
1945       --cache-file=FILE   cache test results in FILE [disabled]
1946   -C, --config-cache      alias for \`--cache-file=config.cache'
1947   -n, --no-create         do not create output files
1948       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1949
1950 Installation directories:
1951   --prefix=PREFIX         install architecture-independent files in PREFIX
1952                           [$ac_default_prefix]
1953   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1954                           [PREFIX]
1955
1956 By default, \`make install' will install all the files in
1957 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1958 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1959 for instance \`--prefix=\$HOME'.
1960
1961 For better control, use the options below.

2020                           only specific categories of checks. Categories are:

17632    Here is a matrix of mmap possibilities:
17633         mmap private not fixed
17634         mmap private fixed at somewhere currently unmapped
17635         mmap private fixed at somewhere already mapped
17636         mmap shared not fixed
17637         mmap shared fixed at somewhere currently unmapped
17638         mmap shared fixed at somewhere already mapped
17639    For private mappings, we should verify that changes cannot be read()
17640    back from the file, nor mmap's back from the file at a different
17641    address.  (There have been systems where private was not correctly
17642    implemented like the infamous i386 svr4.0, and systems where the
17643    VM page cache was not coherent with the file system buffer cache
17644    like early versions of FreeBSD and possibly contemporary NetBSD.)
17645    For shared mappings, we should conversely verify that changes get
17646    propagated back to all the places they're supposed to be.
17647
17648    Grep wants private fixed already mapped.
17649    The main things grep needs to know about mmap are:
17650    * does it exist and is it safe to write into the mmap'd area
17651    * how to use it (BSD variants)  */
