#3840: ghc-6.12.1 takes longer to compile code and produces bigger binaries
compared to ghc-6.10.4

Comment(by maeder):
Interestingly, if I compile the two big files directly, they stay small.
It seems that compiling unrelated modules before increases .o files.
{{{
> ghc --make -DTIME_WITH_TYPEABLE HasCASL/ATC_HasCASL.hs
