I'm talking about the fact that I said that "non-c++" import libraries
should work correctly.  You countered with a question about "Microsoft's
patented virtual table system".

If the virtual table system is used in non-c++ libraries then this is an
issue.  Otherwise, again, non-c++ import libraries should work ok with
'ld'.

The reason that I said "non-c++" is specifically because gcc/gas/ld
don't understand Microsoft's C++ object file layout.
