    Subject[PATCH] 2.4.21-rc1: byteorder.h breaks with __STRICT_ANSI__ defined (trivial)
    Hi Marcelo,

    Here is a patch to fix the following problem (revised as Christoph
    suggested): In 2.4.21-rc1 some inline functions are added to
    asm-i386/byteorder.h. When __STRICT_ANSI__ is defined, __u64 doesn't get
    defined by asm-i386/types.h, but it is used in one of the new inline
    functions, __arch__swab64() - this causes a compile error for any program
    that includes linux/cdrom.h and is built with -ansi. See also Christoph's
    other comments on the list.
