Ok.  This is clearly an issue with \ at the end of lines to
splice them together.  So to a certain the reporting is correct.
But I agree in practice that is wrong.

Fixing this is a little tricky. Either splice_lines needs to
insert a #line directive or I need to cleanup macro parsing a little
more.

Since the only thing incorrect is the line number I would like to
reproduce and fix the mysterious #if 0 does not work bug, before I 
touch that bit of code.
