Allow any of the path or directory Makefile variables to be set with 

flags to configure.  Create all Makefiles at configure time.  Edit
special commands into config.status after src/Makefile.in is built
from src/Makefile.  Don't AC_SUBST rip_paths or inst_paths.

--with-gcc=no Don't use GCC to compile Emacs.
--run-in-place Use libraries and data files directly out of the

--srcdir=DIR Look for source in DIR.
--prefix=DIR Install files below dir.
--single-tree=DIR Has the effect of creating a directory tree at DIR
which looks like:
.../DIR/bin/CONFIGNAME (emacs, etags, etc.)
.../DIR/bin/CONFIGNAME/etc (movemail, etc.)
.../DIR/common/lisp (emacs' lisp files)

.../DIR/common/lock (lockfiles)
--srcdir=DIR Look for the Emacs source files in DIR.
--prefix=DIR Install files below DIR. Defaults to \`${prefix}'.
You may also specify any of the \`path' variables found in Makefile.in,
including --bindir, --libdir, --etcdir, --infodir, and so on. This allows
