[Nut-upsdev] gcc4 noise

Tue Nov 8 06:15:14 UTC 2005

Is anyone besides me using gcc 4.*.*? I noticed that NUT generates an
enormous amount of warning noise with that compiler, mostly due to
implicit casts between signed/unsigned pointer types. Any volunteers
to de-noise the code a bit? The easy way is to insert typecasts; the
better way is to actually take care about signedness. -- Peter
