I have had major problems compiling windows code using mssdk headers using pgcc (1.0.1 I think). The problem was that it was pushing two arguments to TranslateMessage() and DispatchMessage(), and they only take one argument. This lead to a leak of 8 bytes of stack space per message, which causes a mysterious crash a few minutes after starting the program (due to stack overflow). Also, -O6 does enable unstable optimizations. Just read the pgcc faq and see the options labelled as unstable and compare it to the options enabled with -O6 The best commandline for stability is -O6 -fno-loop-after-global -fno-combine-222 -fno-opt-reg-stack -fno-peep-spills although I still had the problem explained above with these options. toudi wrote: > > I have gcc 2.8.1 and it has an option -mpentium, but it does > nothing. > I heard somethin about PGCC.
