Bad, unfortunately, though slightly.
The results below are for an AI system we are developing here (C++,
template heavy) with three different inputs that exercise different parts
of our system.
egcs 19980904 19980907
#1 44.04 user 44.11 user
#2 52.51 user 53.32 user
#2 122.38 user 123.28 user
Compilation flags were -ftemplate-depth-20 -fno-exceptions -O3 -DNDEBUG.
If you're interested, I can e-mail you the sources of the system plus
some testcases.
