Thanks.

Looking at the diff I cannot see any difference between the
two builds in terms of gcc options applied during the compile
and link step.

As you noticed, this leaves the va_list difference which also
causes the warnings in the 32-bit build.

I guess this points to the real cause of the problem: configure
doesn't know anything about BASECFLAGS, but does use CFLAGS for
checking various compiler features, so Antoines command line
options using CFLAGS work, while the ones I posted don't.
