True. I found out what caused the weirdnes a short while later. It
doesn't matter what flags I use in make, a fixed set of warnings is
always enabled.

This makes it hard to check if something fixes the one warning that I wanted to
track down is fixed. By explicitly setting CFLAGS to the equivalent of WARNS=3
or higher WARNS levels all works like a charm :-/
