Compiling Wierdness - changes to code aren't compiled...(seemingly)..

I have made changes to the following code by commenting out all of the printf functions - however, upon recompiling after my changes all data is still printed. What am I doing wrong (I'm sure the problem is me).

It's too much code to post but dl this file and have a look at xev.c (only 80k)

Pre-compiled headers can cause this. Sometimes the compiler doesn't flag the file as dirty and thus it uses the code in the PCH rather than re-compiling your code.

Turn them off temporarily, compile, and turn back on. This should fix it.
