	Is the compiler invoked with the -dA option when testing on HP/UX?
Does that option produce the annotated output for HP/UX GCC target?

	If you refer back to the original discussion of the failure, the
only reason that the testcase succeeds with optimization when using Dwarf2
debugging is the annotation.
