I understood why you had to rename the macro.  The problem is that
I'm wondering what this macro is supposed to be used for.  It's important
because I suspect the change that you made might be incorrect, depending
on the answer to the question above. For instance, I suspect that the
use of the TRACE macro in that file might be related to
--enable-sim-traces, and thus renaming TRACE to something else will break
that.

That's why, IMO, we need to:
  - Understand how --enable-sim-traces work to see if it is related
    to the use of this TRACE macro;
  - Find out how to properly fix your problem;

If you want, I can try doing some digging, but I think it's going to be
a while before I can get to it, which is why I'm giving you as much info
as I have (I really do not have much sim experience, but apparently we
are short in reviewers for the sim code).
