But I care whether gcc barfs on code or not, and whether generated code is correct or not.
I do very trivial 64bit computations in TV-Out portion of matroxfb, but I spent two days shifting code up/down, adding temporary variables and splitting expressions to simple ones to make code compilable at all with gcc-2.95.4 compiling module for PIII kernel (Debian bug #151196). So I personally cannot recommend doing any 64bit math without setting gcc-3.0 as minimal version for ia32 architecture. Petr Vandrovec vandrove@vc.cvut.cz
