-O0 will come out wildly different from an actual build, it stops even
the most basic optimizations -- for instance all variables are put in
actual stack slots (rather than held in registers).
-finstrument-functions is a good alternative to -pg if you want to
know what functions are using up time, though you need a separate
library and whatnot to use it. fnccheck at
http://sourceforge.net/projects/fnccheck
worked for me last time I tried it.
