/* In Tru64 UNIX V5.1, Compaq introduced a new assembler
(/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. */
