------- Comment #10 from mmitchel at gcc dot gnu dot org  2005-10-31 03:49 -------
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.

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