Do we really _need_ the SYMBOL_CPROTO macro? The exported functions are
called from C files presumably, so there ought to be headers with the
declarations. If these headers can't be included easily, we should fix
them, but having copies of the declarations in the asm files is no big
improvement over the asm-prototypes.h approach, IMO.
