gcc 2.95.x doesn't officially support HP/UX 11. If they built it 'out of the
box', it would assume it's compiling for HP/UX 9 and gcc 2.95.x only emits
level for HP/UX 10. Looking at their source distribution, they've made a few
changes but they didn't fix this.

You can hack in rough HP/UX 11 support by duplicating the "hpux10" case in
gcc/configure and creating config/pa/pa-hpux11.h by appending:

	/* Make GCC agree with types.h.  */
	#undef SIZE_TYPE
	#undef PTRDIFF_TYPE
	#define SIZE_TYPE "long unsigned int"
	#define PTRDIFF_TYPE "long int"

(stolen from the gcc 3.0 branch) to pa-hpux10.h. I tried this a while ago
and it bootstrapped OK, I think, but I didn't run the testsuite for reasons
that escape me now.

To do a proper job, though, you probably need to edit the threads fragment
for the specs file and half a dozen other things I'm not aware of. You may
well do better to build and use a gcc 3.0 snapshot since I think that's in
pretty good shape for HP/UX 11 now.
