Should hopefully net me actual dwarf2 debug > symbols. What if you use the GCC --gdwarf-2 option instead of this patch? Does the patch just set the default DWARF version? Seems like if GCC supports DWARF >2, --gdwarf-2 should generate just v2 DWARF info.

I can build up to and including 2.32 with the HP C compiler. Starting with 2.33.1, they add -std=gnu99. Might be possible to fix this but I might retry with 2.32.

It's resolved for HP-UX/PA but my HP-UX/IA patch was never committed.

We prefer to build with HP C and only use GCC when we must. 2.36 didn't build as easily out-of-the-box with HP C and we haven't tried to fix it so we've stuck with 2.30 for newer GCC releases.

If you skip it, do you skip it on earlier GCC builds as well?
