            * doc/install.texi (Specific) <hppa*-hp-hpux*>: Remove a note on
            GCC 4.3.
            Remove details on how the HP assembler, which we document as not
            working, breaks.
            <hppa*-hp-hpux11>: Note that only the HP linker is supported.

-Various GCC features are not supported.  For example, it does not support weak
