Seriously broken.... hmm. That a good thing? :D

No, the aim is to have things in an hilariously broken state ;-)

Ok ... so Strawberry Perl is apparently using the MinGW compiler that shipped with it. Where did you place the other MinGW (ie the one that you mentioned installing in the earlier post) ? Let's give it a whirl and see if it makes any difference.
Assuming it's in C:/MinGW run PATH=C:\MinGW\bin;%PATH% then run gcc -v again. This time the output should be for the MinGW that you installed - which will be different to the one you just posted. That being so, run dmake realclean, perl Makefile.PL and dmake and see if there's any change of behaviour.

Which version of Windows do you have, btw ?

Cheers,
