On a somewhat related note:
I actually have/had a patch for "wide-returns" that allows Higher Order
Messaging to work better with Apple's PPC runtime architecture.
It allows the compiler to skip sign-extending the return value of
methods with sub-word returns, which is useful if you've used
reflective capabilities to redirect a message the compiler thinks
is returning a BOOL to actually return an 'id'.
AFAICT, it never is a problem because gcc actually always returns
a valid full register even for sub-word returns.
