You mean mixing modules compiled with both compilers. Quite time consuming task
if you have a lot of source files (I have only 2...)

Ok, thanks. One question: I have actually only 2 source files. Does the profiler
optimization create the link order based on different functions or just source
files. (I guess the order is based on functions, but I want to be sure)
