All right, I'll try to do something along these lines.

Regardless of *where* getcontext() should be recognized, it's clear that the
compiler should be aware that it has special behavior.  

This is a wrong-code regression on a primary platform with no non-default
options in use; upgraded to P1.

But the place where setjmp is recognized is not in the front-end.

I disagree, the front-end should automatically recognize the function.

This is not a front-end bug.  But I still think it accidentally worked in 
2.95.3 or any compiler really 
because why do we have to treat function special.
