Made a small change to the library compiler scripts so that if they
are presented with a single already-compiled library file, they
keep it rather than delete it.  Also:  Revised the gf180mcu Makefile
to correct for the complete change in structure of the OSU 3.3V
library repository.  The OSU standard cell libraries should now
compile and install properly again.
