g++ does NRVO, which some popular optimising compilers (like VC++ 7.1)
do not do. In my experience, some programs compiled with g++ are
noticeably faster than when compiled with vc++ 7.1, mainly due to the
NRVO. Afaik, NRVO it not implemented in VC++ 7.1 because it conflicts
with the current C++ standard (3.7.2).
