That's gcc, and 4 is the line number (and the wrong line number) of the error. 
No column number.

Tracking the column number is certainly doable, but it comes at a cost of memory 
consumption and some compile speed, since it has to be tracked in every token. I 
used to do it in the Digital Mars C compiler, but it was of only marginal 
utility and I dropped it.
