I have been playing on Mike Meyer's machine to get HP-UX figured out.
The fortran "_" problem is fairly easy to figure out, so I use the
native way of doing things.  The big problem is that autoconfigure
decides that sys/times.h is there, but for reasons that escape me
c89 doesn't seem to find it (gcc does).

I hadn't, but if it lives in the usual system places it should be
simple enough to find and use in place of the portable one.  I'll
modify the setup so this will happen.

Another hard nut seems to be finding out what flags are needed by
cc and ld to set up shared libraries.  This seems to be very platform
