* See iostream/TODO for iostream-specific issues

* Make clean/realclean rules need to be cleaned up.
(waiting for GNU standard to be resolved).

* Use -O.

* Update README.

* Some tests (parts of etc/benchmarks on Iris and DECstation,
etc/lf on Iris) crash on some machines.  They have been taken
out for now.  Figure out what the problems are, and fix them.
Also, put etc/fib back.

* Remove math-68881.h.
