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

2066                           type. This is useful for development for catching
2067                           certain types of bugs.
2068   --enable-profiling      build emacs with low-level, gprof profiling support.

2081                           with older or non-GNU development tools.
2082   --enable-link-time-optimization
2083                           build emacs with link-time optimization. This is

10044    Here is a matrix of mmap possibilities:
10045         mmap private not fixed
10046         mmap private fixed at somewhere currently unmapped
10047         mmap private fixed at somewhere already mapped
10048         mmap shared not fixed
10049         mmap shared fixed at somewhere currently unmapped
10050         mmap shared fixed at somewhere already mapped
10051    For private mappings, we should verify that changes cannot be read()
10052    back from the file, nor mmap's back from the file at a different
10053    address.  (There have been systems where private was not correctly
10054    implemented like the infamous i386 svr4.0, and systems where the
10055    VM page cache was not coherent with the file system buffer cache
10056    like early versions of FreeBSD and possibly contemporary NetBSD.)
10057    For shared mappings, we should conversely verify that changes get
10058    propagated back to all the places they're supposed to be.
10059
10060    Grep wants private fixed already mapped.
10061    The main things grep needs to know about mmap are:
10062    * does it exist and is it safe to write into the mmap'd area
10063    * how to use it (BSD variants)  */
