Why is it that the first thing I try tends to uncover shortcomings?

typedef uint64_t qbb_t __attribute__((vector_size(sizeof(uint64_t) * 4)))

Syntax error

OK, its an extension, meh.

Looking at the project issues, it seems it supports only 1989-era C, and some Apple stuff, before you even get to attributes.

This failed because it doesn't do math: int *x[10/2]
