+   3.04.32) breaks mips-tfile.  Passing the undocumented -oldas flag reverts
+   to using the old assembler (/usr/lib/cmplrs/cc/as[01]).
+
+   The V5.0 and V5.0A assemblers silently ignore -oldas, so it can be
+   specified here.
+
+   It is clearly not desirable to depend on this undocumented flag, and
+   Compaq wants -oldas to go away soon, but until they have released a
+   new adu that works with mips-tfile, this is the only option.
+
+   In some versions of the DTK, the assembler driver invokes ld after
+   assembly.  This has been fixed in current versions, but adding -c
+   works as expected for all versions.  */
