gcc 4.x is used on other platforms, so it's not too new. It's more likely
the alpha code is too old. :-)

I do not actually know what compiler was used for building the alpha port.
Are you using Config.alpha_osf1 or Config.alpha_linux? I think you should
be using osf1. But that seems to be using alpha's C compiler, not gcc.

​What version of the sources are we looking at? There is no line 644 in git
master or RELEASE_18c. And interrupt.c is in ./lisp, not ./src/lisp in 18c,
so I'm really confused at what you're using now.

​AFAICT, alpha does not have an NPC register, so SC_NPC should never be
used.
