It also doesn't for 1.9.6, by the way.

Like you suggest, I would also expect for `COMPILE' and `CPPASCOMPILE' to
behave the same apart from the obvious differences.  But those
differences should not include what `COMPILE' and `CPPASCOMPILE' have in
common: the preprocessing.  And all of the missing bits are pre processor
flags.

I think I don't understand that part.
