	* Makefile.in: Re-write build procedure mainly to honour
	dependencies correctly but also allow making in the build
	directory by configuring the relevant variables.  The lib[FIU]77
	subdirs do dependency checking of their objects.  Stamp files
	dictate when to run (new) archive targets in subdirs.  Some
	tidying of variables.  Supply full set of standard targets.
	* configure.in: Move much of testing to new configures in
	subdirs.  Tidy up handling of RANLIB etc.
	* stamp-h.in, libF77/configure.in, libI77/configure.in,
	libF77/configure, libI77/configure: New files.
	* libF77/Makefile.in, libI77/Makefile.in, libU77/Makefile.in:
	Change in step with libf2c/Makefile.in.

TODO list for the g77 library
* `Makefile.in's should be brought up to standard; I'm not sure they
have a complete set of targets at present.
* Investigate building shared libraries on systems we know about
(probably in 0.5.22, using libtool-1.0 from the FSF, which looks
quite useful).
(probably using libtool).
* Test cases.
* Better test cases.
* Allow the library to be stripped to save space.
* Allow the library to be stripped to save space. (The install-strip
makefile target now allows this, should it be easily invocable.)
* An interface to IEEE maths functions from libc where this makes
sense.
