Fix #line directive

1) Line must set the value for the next line, and since the line
   is incremented at the end of the line, we have to set the
   desired line minus 1.
2) Macros were not expanded in the line directive parameters
3) Lookup was returning macros while it looked up for
   cpp clauses.
