Well, I know that the patch which introduced bitmaps (which was intended 
to be only a performance patch) reversed the logic from right to wrong. 
   The patch for PR17708 already introduced a wrong warning in 2004.

For the record, I don't think it's a bad bug, just a wrong warning, but 
the patch comes at low risk (at worst replacing a wrong warning by 
another wrong warning), but I'll leave it up to your to discretion 
whether to apply or not.
