background:
I have managed to compile ATL/WTL from MSVC6.
I will have available a public patch-file for patching ATL/WTL to compile under wine, Once I have every thing running
Question:
All symbols and functions declared __declspec(selectany) show up as "duplicate symbols" errors on the linker. Eliminating it has the same results.
I have searched in google and the few lines I found is that GCC will accept __declspec(selectany) if "-fms-extensions" is used. Well it will accept it but will only ignore it all together.
Does any body know how to properly merge duplicate definitions of symbols in GCC?
Yes, I think it's attribute((weak)).
(before I go and change the code) maybe a command line switch to the compiler or linker can do the trick ?
Part of the solution might be to apply the following patch to the gcc-3.3 source tree:

I suspect the folks who did the original ms-extensions for gcc never figured we'd be compiling Windows source code on Linux, but here we are... - Dan
