Good question.  The old code had:

    ...
    #else                           /* i386 probably */
    typedef unsigned char slock_t;

    #endif

Doesn't engender confidence, does it?  Seeing as it used to work, I have
added:

    #elif defined(__sparc__)
    typedef unsigned char slock_t;

so it now explicitly has this lock for sparc, rather than falling into
an #else that could be any cpu.
