This is definitely our bug, not GCC's:

C99 6.7.6.2p1:
  The optional type qualifiers and the keyword static shall appear only in a declaration of a function parameter with an array type, and then only in the outermost array type derivation.

So please file your bug at http://llvm.org/bugs/ rather than gnu.org. :)

This should be simple for us to check and fix.
