That's good to know.  We should add 11.31 support and make lonking
with unix2003.o the default.

So, we have:
HP-UX 10.*: no snprintf
HP-UX 11.[0-2]*": non standard snprintf
HP-UX 11.31: C99 snprintf with unix2003.o

In my opinion, the testcase should be testing the GCC implementation
of snprintf.  If any of the four cases are not optimized by GCC, they
should be removed.  The HP-UX issues with snprintf aren't unique from
what I see on the net.
