Yes, that's the better solution.  It will probably just upset a lot of
people's thinking.

The main problem way back when I last considered this seriously was that
it wasn't clear how many compilers don't support -o with -c.  The paper
doesn't offer a clear solution to that, but it might be that the problem
is effectively gone now.
