__LINE__ is a builtin macro that expands to a decimal constant.
__FILE__ is another that expands into a string.  

There are also goodies like __DATE__ and __TIME__.  Google Predefined 
Preprocessors Macros for a list.

I'm pretty sure MSVC++ has both __CLASS__ and __FUNCTION__.  All the gnu 
compilers have __FUNCTION__ and __PRETTY-FUNCTION__ (which gives class info).

And yes, I found out most of this after I had larded up thirty files with

#undef CLASSNAME
#define CLASSNAME ("YetAnotherClass")
#undef FUNCNAME
#define FUNCNAME ("YetOneMoreFunction")

Getting to remove all of those was a red-letter day.
