Just making sure you are aware of 

  http://hpux.cs.utah.edu/hppd/hpux/

Which has precompiled binaries for many useful things on hpux.

If you are using off64_t then you need to have _FILE_OFFSET_BITS=64
defined somewhere.  I do not see -D_FILE_OFFSET_BITS=64 anywhere.  It
might be in the config.h file.

But you should not have gotten HAVE_FOPEN64 defined if you did not
that.  Which is contradictory evidence.

Yes, if you do not compile in LP64 mode, which on 10.20 you can't.
You need 11.x or later for LP64 mode.  Which is the whole reason for
the off64_t being defined with _FILE_OFFSET_BITS=64.

Check your config.h and see what _FILE_OFFSET_BITS is set to.  If you
are using off64_t then you need _FILE_OFFSET_BITS=64.  autoconf-2.52
and later have built in support for this.  Earlier versions need
manual help to force that mode.  If the configure is old then it won't
have this by default and you will have to help it.

That is pretty old to the point of being a little scary.  I would feel
better if you had said 2.95.[23] which work pretty well on hpux 10.20.
