Re: MS compatible DLL's with cygwin32 (fwd)

Look at the mangled names in your dll.
Look at the mangled names in the VC++ dll.

Use Dlltool to create an import library

def file
EXPORTS
MSmangledname=g++mangledname

I don't know that this will work, but it is the only
possibility I can see.

We really need a tool that will translate VC++
cplusplus names to g++ names, does anyone
know how to do this?
