Hmm, I didn't catch this because I was using gcc 3.1 for compiling
(which yields slightly faster code -- compilation takes longer however).

It suspect that the option -Wp,lang-c89 should take care of forcing a
failure here. However, I cannot find this option in either the
documentation of gcc-2.95.3 nor 3.1
I can force gcc 3.1 to produce a warning there with -ansi -pedantic. But
that causes tons of other warnings due to the variadic macros.

I guess I will switch back to gcc 2.95.
