Ah, I suppose you mean the 'E:\8168\vc98\mfc\\src\mfc42.pdb' 
line. There is no such file. In fact, I don't even have a drive mapping 
for E:. I've been assuming that winedbg is getting this bogus path from 
the executable (perhaps the location of MFC42.PDB when MFC42 was 
originally compiled or something).

I ran the ChkMatch tool from to verify that the PDB 
and DLL really match, and it also confirms that the bogus E: path really 
comes from MFC42.DLL. This doesn't rule out the (rather unlikely, I 
would say) possibility that the PDB is corrupt in some other way, of 
course. Perhaps someone can mail me a "known good" pair of MFC42.DLL/PDB 

[palm at localhost tmp]$ wine ChkMatch.exe -c
