I don't think that's true.

Actually, -O3 is not the best choice overall. Try -O2 and see if it's
better.

Please donwload the DJGPP FAQ list (v2/faq211b.zip from the same place
you get DJGPP) and read section 14.2 there, then try using that advice.
I hope this will be a good beginning. If it doesn't help enough, try
asking specific questions here.

The best test case is your own application(s).

No, you cannot mix object files from different compilers. But I don't
understand why do you have to, since DJGPP programs will run on Windows
9X as well (and support long file names, btw).
