g++ v3.5.0 produces slower code than v3.4.1 for some loop-intensive algorithms.
Also, the fomit-frame-pointer switch seems to act as a "de-optimization" switch
for some of the attached code (unlike v3.4.1, for which the fomit-frame-pointer
switch seems to make for faster executables for most applications).
