[patch] ia64/bits/sigcontext.h

[Jes Sorensen]

Hi

Included is a patch to add definitions for the sc_flags bits in 
struct sigcontext on ia64.

The patch was generated against libc-2.2, but should apply cleanly to
2.3 I assume (can't seem to be able to get a cvs update from
sources.redhat.com right now ;-().
