Mwtypes.h line 32:
#if defined(GCC_VERSION) Should be: #if (defined(GCC_VERSION) && (GCC_VERSION >= 2093)) || (defined(__GNUC__) && (((__GNUC__ >= 2) && (__GNUC_MINOR__ >= 95)) || (__GNUC__ > 2))) Like it is in device.h On my system, GCC_VERSION is not defined and caused screen.bmp screen dump output file to be aligned wrong. Now it is working fine. Martin
