i haven't compiled on hp-ux for quite a while - but my experience on that
platform and solaris are to __always__ compile using

   - gcc
   - glibc

to avoid issues with the builti-in (broken) c compilers.

we setup a

   /gnu/

partition where we could install all the gnu tools and then used those when
compiling via

   export LD_LIBRARY_PATH=/gnu/lib
   export LD_RUN_PATH=/gnu/lib
   export PATH=/gnu/bin

   export CC=/gnu/bin/gcc

   ./configure --prefix=/usr/local && make && sudo make install

hth.
