This is misunderstanding. GCC 3.4.3 provides *correct* CPP behavior, 
while all 4.x provides broken CPP. That means as a workaround when GCC 
3.4.3 is installed I set it as GHC's CPP automatically on Solaris. When 
it is not available, then GHC behaves like you've seen when using CPP...

Hopefully this is more clear now,
