The "-mpa-risc-2-0" switch worked for 3.3.6 and 3.4.5:

file gcc-3.3.6/lib/gcc-lib/hppa2.0w-hp-hpux11.00/3.3.6/gnat1
gnat1:          PA-RISC2.0 shared executable dynamically linked -not stripped

file gcc-3.4.5/libexec/gcc/hppa2.0w-hp-hpux11.00/3.4.5/gnat1
gnat1:          PA-RISC2.0 shared executable dynamically linked -not stripped

I have to leave the office now. I will investigate further tomorrow.
