C++ exception problems in mingw cross compiler

Right. What did not seem clear after in the discussions about this 
problem, was whether I needed a patch or just special build options, or 
both... Thanks for clarifying.

I'm still not 100% happy, though (some people are just never satisfied 
;-/), as I'd very much prefer to have patches as, well, just patches - 
instead of updated source trees. Do you happen to know if the changes 
are available in patch file form anywhere? I haven't been able to find 
anything on the MinGW sourceforge sites - but I'll keep looking...
