This approach didn't work either (though I didn't try too hard as well), 
as they produce c++ code and compile with g++, I preferred not to pursue 
 this, though it looks like a very useful system for user-mode programs.

I ended up doing a non-C parsing aspectizer in a very simply Python 
script that modifies the code according to my needs, which are pretty 
simple, just wrap a function in another function and log the rdtsc timer 
 at entry and exit. The Python script "parses" by the known signatures 
that I give it which means it's not very robust but "works for me".
