This breaks my nightly build:

$ gcc packssdw-1.c
In file included from packssdw-1.c:1:
/usr/lib/gcc/i486-linux-gnu/4.3.4/include/emmintrin.h:34:3: error:

packssdw-1.c:4: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ 
before ‘foo’
packssdw-1.c: In function ‘main’:
packssdw-1.c:11: error: ‘__v4si’ undeclared (first use in this function)

packssdw-1.c:6: note: use -flax-vector-conversions to permit conversions 
between vectors with differing element types or numbers of subparts
