make[4]: *** [swrast/s_texfilter.o] Error 1
I've reproduced the error, preprocessed source is
paer.debian.org:~jcristau/mesa-7.0.2/obj-hppa-linux-gnu/debian-osmesa16/src/mesa/swrast/s_texfilter.i
(not attached here because it's over 600k).
It builds fine with gcc-4.1, but not with gcc-snapshot 20070916-1.
Cheers,
Julien
