I think you have this backwards. On OpenBSD/sparc64 $ gcc -dM -E - < /dev/null | grep BIG $ $ sysctl hw.byteorder hw.byteorder=4321 endian.h defines BYTE_ORDER and it should be included to test it. I was under the impression the headers on linux had similiar defines. Look at how src/gallium/include/pipe/p_config.h does it. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
