Hi Gerald, I have one comment. The only target currently supported is hppa64-hp-hpux11*. While gas is required, only the HP ld works. Otherwise, the change looks fine.

I updated the patch accordingly, referring to gas (not gas/binutils) and being explicit around the flavor of ld to use, and pushed it. Any further comments or suggestions, let me know.

John, Jeff, I suggest to streamline the hppa*-hp-hpux* installation instructions as follows. Okay? In fact in the following sections there is even more, and more specific material, which would be great could you have a look at and help trim.
