Routine Description:
Given the line number in the preprocessor-output file, use the line number
information we've saved to determine the source file name and line number
where the code originally came from. This is required for error reporting.
Arguments:
LineNum - the line number in the preprocessor-output file.
Returns:
Returns a pointer to the source file name. Also returns the line number
in the provided LineNum argument
