Re: CCP4

   Have any of you built the CCP4 crystallographic
suite with gfortran? I just finished making new
multilib packaging for PPC and Intel Darwin using
the current gcc 4.2 shapshot and the fink maintainer
of ccp4 complained of some breakage in his package.
I discovered that ccp4 was using makefiles adjusted
for gcc 4.0.2 which had whole directories being built
at -O1 and -O0. Bumping everything up to -O3 and
using the shared library support eliminated the
segfaults that the ccp4 maintainer complained about.

It works correctly at -O3, but breaks at -O1 and -O0? That seems rather concerning! Is there some reason I'm missing why this is innocuous?
