	This may depend on the type of symbol.  I do not know how class
names appear as symbols and how this would appear in an exports list.  A
class name is not an actual method or member.

	As mentioned in the README.RS6000 file, AIX 4.1 linker became much
more pedantic about warning of duplicate symbols.  These always have been
there and should not affect correctness of the resulting executable.
