I get the following when trying to link one of the STLSoft unit-test 
programs.

I'm guessing that there aren't enough symbols used to discriminate 
between records, but it's all conjecture.

(Am using DMC++ 8.44 b3, btw; also happens with 8.43)

Cheers

Matthew

All it means is that the same symbol is defined in multiple .obj files.

Well, duh! Of course that's what it means. That's obviously not 
where the problem lies.

What I'm saying is that it's wrong, or to be more precise: either 
the linker is correctly detecting that the compiler is making 
multiple instances of something for which there should only be one, 
or that the linker is not correctly coallescing multiple definitions 
into one, as dictated by the language inlining rules. And the 
confidence with which I say this, and made the original post, over 
and above the fact that I'm doing something C++-sensible is that 
about 16 other compilers compile and link an executable from the 
same sources successfully.

Anyway, I've found a workaround now. Just one more #ifdef 
STLSOFT_COMPILER_IS_DMC ... ;-(

If you can isolate it down to a small test case, I can take a whack at it.
