My C (not vim) solution for this is:

#define BUGOUT( FMT, ... ) { \
fprintf(stdout, "%s: %5d:%-24s:", __FILE__, __LINE__, __func__ ); \
fprintf(stdout, FMT, ##__VA_ARGS__ ); \
fflush (stdout); \
}

and is used as a standard printf(), i.e.:
BUGOUT("text: %d %s\n", num, string ) // For example

The output shows the filename, line number, and function the debug statement occurs. Always correct and easily found in the source.
