Multiply defined symbols during linking...

[Rick Harding]

Attached is a uuencoded tar'd, gzip'd test case that illustrates the
problem.

The virtual functions defined in the template class MValue in file F.h
(necessary due to the inheritance from the abstract base class Base)
seem to be causing the problem. If you eliminate the virtual functions
it will link just fine.

This very same code compiles on EDG based compilers such as MipsPro
7.0.1 under IRIX 6.2.
