# Gets build, host, target, *_vendor, *_cpu, *_os, etc.

# You will slowly go insane if you do not grok the following fact:  when
# building v3 as part of the compiler, the top-level /target/ becomes the
# library's /host/.  `configure' then causes --target to default to --host,
# exactly like any other package using autoconf.  Therefore, 'target' and
# 'host' will always be the same.  This makes sense both for native and
# cross compilers, just think about it for a little while.  :-)
#
# Also, if v3 is being configured as part of a cross compiler, the top-level
# configure script will pass the "real" host as $with_cross_host.
#
# In AC 2.13 AC_CANONICAL_TARGET was known as AC_CANONICAL_SYSTEM.

# Do some error checking and defaulting for the host and target type.
# The inputs are:
#    configure --host=HOST --target=TARGET --build=BUILD NONOPT
#
# The rules are:
# 1. You are not allowed to specify --host, --target, and nonopt at the
#    same time.
# 2. Host defaults to nonopt.
# 3. If nonopt is not specified, then host defaults to the current host,
#    as determined by config.guess.
# 4. Target and build default to nonopt.
# 5. If nonopt is not specified, then target and build default to host.

/* Thanks to Mike Haertel and Jim Avera for this test.
   Here is a matrix of mmap possibilities:
        mmap private not fixed
        mmap private fixed at somewhere currently unmapped
        mmap private fixed at somewhere already mapped
        mmap shared not fixed
        mmap shared fixed at somewhere currently unmapped
        mmap shared fixed at somewhere already mapped
   For private mappings, we should verify that changes cannot be read()
   back from the file, nor mmap's back from the file at a different
   address.  (There have been systems where private was not correctly
   implemented like the infamous i386 svr4.0, and systems where the
   VM page cache was not coherent with the filesystem buffer cache
   like early versions of FreeBSD and possibly contemporary NetBSD.)
   For shared mappings, we should conversely verify that changes get
   propogated back to all the places they're supposed to be.

   Grep wants private fixed already mapped.
   The main things grep needs to know about mmap are:
   * does it exist and is it safe to write into the mmap'd area
   * how to use it (BSD variants)  */
