--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So, where would be the best place to remove the VLA bounds from parameters of
fn declarations?  Some function called from c_write_global_declarations_1 and
from walking BLOCK tree vars e.g. right before calling c_genericize in
finish_function?
