Hum. That's a valid concern for some platforms, Sparc I think?

But I'm skeptical that it would hit such a wide swathe of the build farm. In
particular AFAIK the standard ABI for i386 does no such thing. You can get
behaviour like that from GCC using function attributes like regparam but it's
not the default.
