You might consider trying your code on other systems to see what they do.
Here's what I get on FreeBSD, for instance:
% ./a.out
rounding direction before setjmp is 0
rounding direction changed to 1024
status = 15
rounding direction after longjmp is 0
If you find that other OS's do the same thing, I suggest adapting your code to work with this behavior.

The only other OS I have easy access to is linux. There I get the same behavior as Panther:

For what it's worth: ---------- % cc -o tj testjmp.c % ./tj

rounding direction before setjmp is 0
rounding direction changed to 1024
status = 15
rounding direction after longjmp is 0
% uname -s -m -r
HP-UX B.11.23 ia64
% cc -V
