+1.

Out of curiosity, I made a quick script to see if we had any candidates for
bugs related to this. I didn't expect any bugs to be found, since with the
amount of static checkers that have been run they should have been found.
The only problem I found was in the S390 port of libffi (#ifdef-conditional
code which wouldn't even compile).

I also found (in ast.c) two instances of semantically correct code with the
wrong indent level which I fixed (see rev 1ececa34b748).

cheers,
Georg
