gcc-4.4 optimizations question
I saw this on gcc devel ML:

Because the behavior of -O3 must not depend on whether optional libraries
are linked into GCC, and we did not decide to make PPL and CLooG required
to build GCC, so -O3 cannot enable any optimizations using optional
libraries.

Does our gcc-4.4 have these optional libs?
