Stuff from bison contains #line directives.  This makes sparse ignore
such lines.  This helps but doesn't exactly make sparse happy over such
.c files.

(Ignoring isn't quite right because, arguably, later error messages should
refer to the file from which the c code was generated, not from the c code
itself.)
