Please document carefully what you are doing. Preferably including taking a
snapshot of the mingw installation etc.

This weekend, I tried to duplicate building the FPC IDE with mingw (as
prepared by Mario M. in mantis 11968)

I succeeded partially (can set breakpoints and trace the source), but
somehow program termination crashes GDB which then refuses to shutdown. I
suspect that I didn't properly init mingw to begin with. (I fake _atexit)

I keep tabs on 

http://www.stack.nl/~marcov/mingw/

but I still have to update that for recent events.
