Argh, I wish GCC cross-compiler wasn't so dumb. It does require -isystem despite --sysroot. It's working currently due to a mistake of having X_COMPILER_TYPE set even for native GCC builds. This is just a reminder that GCC --sysroot is not nearly as useful and obvious as clang's. I'm unwinding some bugs from this and other related X_COMPILER changes. -- Regards, Bryan Drewery
