With GCC4 (CVS HEAD) I can't compile the test case:  
  
t.cc:1: warning: specifying vector types with __attribute__ ((mode)) is  
deprecated  
t.cc:1: warning: use __attribute__ ((vector_size)) instead  
t.cc:1: error: mode 'V2SF' applied to inappropriate type  
t.cc: In function 'vec2f mul(const vec2f&, const vec2f&)':  
t.cc:26: error: '__builtin_ia32_pfmul' was not declared in this scope  
  
With gcc 3.3.4, I also get:  
t.cc: In function `vec2f mul(const vec2f&, const vec2f&)':  
t.cc:28: error: `__builtin_ia32_pfmul' undeclared (first use this function)  
t.cc:28: error: (Each undeclared identifier is reported only once for each  
   function it appears in.)  
  
For the C test case, I get: 
t.c: In function `mul': 
t.c:15: error: cast to union type from type not present in union
