For consistency, leave the array name unsized. There are arguments either way, but this only triggers an error if there are too many initializers, not too few, so it is only a partial sanity check. It would be better to add a gdb_assert that the size of the array is the same as OAEM_NUM_REGS. But if so the change should be a) made in a separate commit and b) be done for all the arrays. For now I suggest leaving it unsized.
