if you wanted to add it while debugging, that's fine, but the point is that 
this doesn't belong in normal runtime images.  it's even trivial to define such 
a macro:
#ifdef DEBUG
# define printf(fmt, args...) printf("%s:%s:%i: " fmt, __FILE__, __LINE__, 
__func__, ## args)
#endif
(will obviously need a little more work to handle non-const fmt strings, but 
you get the idea).
