Ulrich, are you sure that Alpha is big-endian?

I don't think so!

paolo:/usr/src/linux/include/asm-alpha>tail byteorder.h
#define __arch__swab32 __arch__swab32

#endif /* __GNUC__ */

#define __BYTEORDER_HAS_U64__

#include <linux/byteorder/little_endian.h>

#endif /* _ALPHA_BYTEORDER_H */

On the other hand:
paolo:/usr/src/linux/include/asm-sparc>tail byteorder.h
#include <asm/types.h>

#if defined(__GNUC__) && !defined(__STRICT_ANSI__) || defined(__KERNEL__)
#  define __BYTEORDER_HAS_U64__
#  define __SWAB_64_THRU_32__
#endif

#include <linux/byteorder/big_endian.h>

#endif /* _SPARC_BYTEORDER_H */

However, as I already told you I cannot find positive testresults for
sparc-linux... Have you really seen them?

Ciao,
Paolo.
