Thanks, I just invoked 'man gcc' and got the documentation for gcc-2.95.
Do you know, why this has changed? For me, it does not make sense.> If you change -I to -isystem, then the right thing should happen; not > sure about that though. Yes, that works (so I now use `gtk-config --cflags | sed "s/-I/-isystem /g"`). Thanks Diether Knof
