  Log Message:
  -----------
  preproc: Fix macro definition lines being offset by 1

This is most noticeable in preprocessor messages involving the
definition location of a macro (redefine warning, argument mismatch
errors). The preprocessor_data linenum_ variable never starts at zero as
far as I can tell.
