If you try to have a constant array of vectors on gcc-3.4.3 you you may get
parse errors when they shouldn't.
All seems related to the vector definition and where you place the const 
attribute.
If you define each array element constant and vector is defined as __vector ->
__attribute__((altivec(__vector))), you may get a parse error; if vector is
defined as __attribute__((vector_size(16))) all works.

If isn't a parser bug, is a documentation issue.

please look at the testcase for further details
