That's the idea of hints. Telling you you need to look at the code once, 
and if it's ok => good. But if the hint was correct => fix it.

This was in reply to

which would suppress *all* hints of the "uninitialized" type. => Which 
means you may lose possible valuable hints.
It defeats the idea of hints to turn them off globally (even if only 
specific hints).
You need to turn them off locally only.

This does not solve (but did not reply to neither) the case where if a 
hint for FillChar is generated, this hint is always wrong. (hence I 
changed the subject)
