Nah, pgcc never was fast for me. Only slower.
Using just -O2 -mpentium with pgcc was 15% faster as
using -mpentiumpro  with it.

SO FOR NATIVE pentiumpro it was slower.

Note that best settings of pgcc never came close for me in neighbourhood
of gcc still!

I just learned that the code size of diep-engine is 460kb when
compiles with visual c++. That's the engine. Not the interface.
Of course a part of this is book code as engine handles book in
my prog. and a part of it is EGTB code.

Yet still it's huge in any respect. So if a compiler goes fiddling
with it then it is going to fall outside of *anything*.

Not to mention if run dual.

Quad is a different case as caches are bigger there...

I've given up PGCC in all respects. What i heart was that they did
some effort for 64 bits and old K6 computers though.
