We are planning to support g++ under HP-UX10.20 not under version 9.
We already tried to generate the g++ version under version 9.
We succeeded in all the compilation steps but failed in generating
the libraries.
We already have the installation procedure in the root.cmz file
for hpux and g++. If you are still interested to investigate,
let me know. I will give the instructions to install from scratch.
