Hmmm, I thought: "Let's tell him about the mcount-bug", but if you say
that's fixed... If nothing else works, try compiling with -O2 or -O3
(it _does_ work with -pg), maybe with -minline-functions. This gets
rid of much of the function calls, which might speed things up, but
this also means you can't profile those functions.

I hope someone else has got a better answer for you :)
