Bill,

We had some discussion on this yesterday. The plan is to "try to" merge 
these with the enter/exit macros eventually. The current commit is just 
a place holder, since this is not trivial. Some things we need to 
consider are:

1. The trace macros take more parameters than just the function name 
that FUNC_ENTER/EXIT take.

2. The macros are called with different parameters in different code 
paths (e.g., success and failure).

Once we have the code we want to take in the branch, we can figure out 
how to correct it.
