Apologies for this blast from the past. As you can see I'm nearly 7(!)
months behind in the mailing list. (But I'm catching up!)
All the FAQ says about this is the following:
Q. Can I mix objects compiled with msvc++ and gcc?
A. Yes, but only if you are combining C object files. MSVC C++ uses
a different mangling scheme than GNU C++, so you will have
difficulties combining C++ objects.
I'd like to include the extra detail that Robert goes into, if it's
correct. Does anyone know for sure?
Thanks for your help.
Regards,
David
