You are right, for some reason I was thinking of gc_os_dep.c as a header
file and thinking that continuations.c and gc.c would see the
definition. My change would break IA64 Linux but I didn't see that
because I was testing on IA64 HP-UX where I didn't want IA64 defined
anyway.

The code might work for other OS's, the problem on HP-UX is that HP-UX
made ucontext_t an opaque type and then provided access functions to get
the information that guile is trying to access directly from ucontext_t.
If the other OS's provide ucontext_t and let you access it directly the
code might work there.

I did try 1.6.8.rc0 and got the same results.

Given that things don't work with 1.6.8.rc0 even after changing __ia64__
to IA64 I think it is reasonable not to address this problem for 1.6.8.
I'd like to get guile working at some point on the HP-UX IA64 platform
but I don't know if that means getting the 1.6.* branch to work or if I
should just look at the top-of-tree sources.
