I'm not convinced this is the correct approach. It is not so bad for
kprintf, because if the attribute is not available, all that happens is
that you loose potential warnings. But for return_in_regs, the way your
code gets compiled will change. Personally, I think it would be a bad
idea to deliberately go in a direction where the only compiler that can
ever compile the kernel & other netbsd sources is the one maintained by
members of this list (For a start, it would make starting new ports more
Secondly, I don't like littering CPP with gazillions of pre-defined
pre-processor options describing the compiler's capability. It would be
much cleaner if this could just be worked out where needed from the
standard definitions (compiler major and minor release numbers).
