Barry, I highly recommend you to use the static counter too otherwise 
you won't catch the following bug:

if all processes should call "n" times the same line of code (then the 
same __LINE__ and __FILE__) but one process do not make the right number 
of call...

Also, it is not a big deal to have this static value in a function, so 
it shouldn't be a big issue...
