And just for the sake of completeness: GAR doesn't add such optimization
flags when you set GARFLAVOR=DBG. Just give

  GARFLAVOR=DBG gmake modenv

a try and GAR will tell you what flags it will use. This doesn't mean that
GAR will filter out such flags for you when you have set them manually
elsewhere, but it won't produce them on its own.
