+Building GCC on this target requires the GNU Assembler. The bundled HP
+assembler will not work. To prevent GCC from using the wrong assembler,
+the option @option{--with-gnu-as} may be necessary.
+
+The GCC libunwind library has not been ported to HPUX. This means that for
+GCC versions 3.2.3 and earlier, @option{--enable-libunwind-exceptions}
+is required to build GCC. For GCC 3.3 and later, this is the default.
