Broken compiler? What ends up as constants may be "computed" by cpp and depending on options and platform specifics need not always be constant. How is it expected to be "fixed"? Besides, despite "sizeof(foo)" being a constant, you can't move a comparison against it to cpp. > > It's valid C. > > Never said it wasn't -- those are warnings, not errors. Unjustified, unless perhaps for debugging the compiler itself. It could equally well complain about int-type constants used to initialize "long int" variables... I'd suggest adding an autoconf test to disable such useless warnings. Maciej
