Abort
A bitfield defined with type "la", where "la" is a typedef for "long
__attribute__((aligned (8)))", is correctly aligned... until you pass
-funsigned-bitfields. If you do that, the bitfield changes from "long" to
"unsigned long" (correctly), and all its attributes are discarded
(incorrectly).
