Yeah, it handled the 10MB (!!!) Qt .cpp just fine from PyQt...  This
is apple's gcc 4.0.1 build 5250 (which is gcc 4.0.1 plus a bunch of
vendor-specific patches)

Hm, I get the same error after rerunning it with -i, I just end up
with 29 .cpp files this time, the first of which fails:

This smells like the kind of error I got when fixing bad KDE_EXPORT
defines in other parts of KDE (my KDE has -fvisibility=hidden
enabled).

If it helps, I've got the pre-parsed gcc -E output at
http://ranger.befunk.com/debug/sipkpartscmodule.generated-cpp.bz2
(warning, about 285k compressed).
