1971 \`configure' configures emacs 24.3.50 to adapt to many kinds of systems.
1972
1973 Usage: $0 [OPTION]... [VAR=VALUE]...
1974
1975 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1976 VAR=VALUE.  See below for descriptions of some of the useful variables.
1977
1978 Defaults for the options are specified in brackets.
1979
1980 Configuration:
1981   -h, --help              display this help and exit
1982       --help=short        display options specific to this package
1983       --help=recursive    display the short help of all the included packages
1984   -V, --version           display version information and exit
1985   -q, --quiet, --silent   do not print \`checking...' messages
1986       --cache-file=FILE   cache test results in FILE [disabled]
1987   -C, --config-cache      alias for \`--cache-file=config.cache'
1988   -n, --no-create         do not create output files
1989       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1990
1991 Installation directories:
1992   --prefix=PREFIX         install architecture-independent files in PREFIX
1993                           [$ac_default_prefix]
1994   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1995                           [PREFIX]
1996
1997 By default, \`make install' will install all the files in
1998 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1999 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2000 for instance \`--prefix=\$HOME'.
2001
2002 For better control, use the options below.
2003
2004 Fine tuning of the installation directories:
2005   --bindir=DIR            user executables [EPREFIX/bin]
2006   --sbindir=DIR           system admin executables [EPREFIX/sbin]
2007   --libexecdir=DIR        program executables [EPREFIX/libexec]

2058   --enable-checking[=LIST]
2059                           enable expensive run-time checks. With LIST, enable
2060                           only specific categories of checks. Categories are:
2061                           all,yes,no. Flags are: stringbytes, stringoverrun,
2062                           stringfreelist, xmallocoverrun, conslist, glyphs
2063   --enable-check-lisp-object-type
2064                           enable compile time checks for the Lisp_Object data
2065                           type. This is useful for development for catching
2066                           certain types of bugs.
2067   --enable-profiling      build emacs with low-level, gprof profiling support.

2071                           Requires GNU Make and Gcc. Enabled if GNU Make and

2074   --enable-dependency-tracking   do not reject slow dependency extractors
2075   --disable-largefile     omit support for large files
2076   --enable-gcc-warnings   turn on lots of GCC warnings. This is intended for
2077                           developers, and may generate false alarms when used
2078                           with older or non-GNU development tools.
2079   --enable-link-time-optimization
2080                           build emacs with link-time optimization. This is
2081                           supported only for GCC since 4.5.0.

10035    Here is a matrix of mmap possibilities:
10036         mmap private not fixed
10037         mmap private fixed at somewhere currently unmapped
10038         mmap private fixed at somewhere already mapped
10039         mmap shared not fixed
10040         mmap shared fixed at somewhere currently unmapped
10041         mmap shared fixed at somewhere already mapped
10042    For private mappings, we should verify that changes cannot be read()
10043    back from the file, nor mmap's back from the file at a different
10044    address.  (There have been systems where private was not correctly
10045    implemented like the infamous i386 svr4.0, and systems where the
10046    VM page cache was not coherent with the file system buffer cache
10047    like early versions of FreeBSD and possibly contemporary NetBSD.)
10048    For shared mappings, we should conversely verify that changes get
10049    propagated back to all the places they're supposed to be.
10050
10051    Grep wants private fixed already mapped.
10052    The main things grep needs to know about mmap are:
10053    * does it exist and is it safe to write into the mmap'd area
10054    * how to use it (BSD variants)  */
