Yes, I could see that that's how the DLL rule on the line below differed.
I wasn't sure how to make a makefile template that could include the def
thingy correctly, and more importantly don't have a Win32 machine to test
on, so didn't try.
(Actually, I was on the tube at the time, so my options were somewhat limited)

I'm not sure how to interpret that trace to work out whether the crash is
