gcc internal variables

Does gcc have any internal variables for what file its compiling and what line its on?

Something like...

Code:

printf("%s : %d\n", __file__, __line__);

Yeah, since this feature is part of standard ANSI C. The following preprocessor symbols are defined:

__LINE__ current line number
__FILE__ name of the file being compiled
__DATE__ date (in string form)
__TIME__ (time (in string form)

(that's two underscores befre and after each symbol)
