        Rebuild on hpux.

HP-UX 10 and 11 don't have altzone.  I hacked strftime.c to work around
this problem.

I should note that this isn't a complete fix for strftime.  I noticed
the `zone' is used before it is initialized by gettimeofday.  Actually,
using gettimeofday is an alternate solution for HP-UX, but it doesn't
have the timezone function.
