Actually, I would encourage you instead to obsolete fixinc.dgux and
convert it to the new fast fixincludes scheme.   This way you'll get
this fix (and others) at no recurring cost.   The process would
look something like this:

1) Make a copy of gcc/include.
2) Whack the special casing in mkfixinc.sh for dgux.
3) Examine fixinc.dgux for fixes that need to be ported into inclhack.def.
   By my cursory reading, there is one one "real" fix in fixinc.dgux and it
   seems to matter only on 88K anyway.
4) Rerun the fixer.
5) Compare gcc/include against your saved tree.  Confirm that nothing is 
   more broken than it used to be.
6) Bask in the glory.
