Package: kernel
Version: 2.4
Severity: grave

Heavy dependencies on the siginfo_t contents, for example in
<bits/siginfo.h>, leave few clean alternatives for making the
32/64-bit structs align in reasonable ways.  glibc
pokes right into this structure (rt_sigqueueinfo) and it is delivered
to signal handlers which shouldn't but might use its contents.  This
sucks rocks but must be fixed, probably with lots of ugly wrappers.
