A few years ago we got SGI's IA-64 kernel to compile with their Pro64 compiler. Despite the usually rather dramatic superiority of Pro64's code generation compared to the gcc of that time - half the time to generate twice as fast application code was common - the huge effort it took was essentially wasted time to achieve a hard to meassure amount of extra performance. Most of the kernel code is well optimized, was written with being compiled by gcc in mind and performance is more limited by the hardware and kernel algorithms than by the compiler's code generation. So I wouldn't invest any time into trying to get the kernel working on yet another non-gcc compiler ... Ralf
