It worked on my 2.95.2 collector's item cross compiler... Oh, and the 
export table does indeed show the foo() function as well.

(BTW, the native objdump works just as fine as the one that belongs to 
the cross compiler. As expected, since it's based on libbfd, I suppose.)


Anyway, unless I'm missing something, we still need import libs to be 
generated for compilers that can't link DLLs directly. I've just looked 
at a few DLLs, but it seems to me that objdump -p <DLL> digs the required 
info out. Here's the interesting part of the output from SDL.dll, for 
example:

[Ordinal/Name Pointer] Table
        [   0] SDL_AddTimer
        [   1] SDL_AllocRW
        [   2] SDL_AudioDriverName
        [   3] SDL_AudioInit
        [   4] SDL_AudioQuit
        [   5] SDL_BuildAudioCVT
        ...

Has anyone tried hacking a script to turn that into a .def file? Or 
should I, or someone else, just try to add a feature to objdump?
