+ (/usr/lib/cmplrs/cc/adu) which currently (versions between 3.04.29 and
+ 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. */
