Bah, typo (f not handle), still untested :) 
void
setbuf(handle, ...)
    OutputStream    handle
    CODE:
    if (handle)
#ifdef PERLIO_IS_STDIO
        {
        char *buf = items == 2 && SvPOK(ST(1)) ?
          sv_grow(ST(1), BUFSIZ) : 0;
        setbuf(handle, buf);
    }
#else
    {    /* not_here("IO::Handle::setbuf"); */
        
        PerlIOBuf * const b = PerlIOSelf( handle, PerlIOBuf);
        PERL_UNUSED_CONTEXT;
        if(items == 2 && SvPOK(ST(1)) )
        {
            b->bufsiz = SvLEN(ST(1));
            Newxz(b->buf, b->bufsiz , STDCHAR);
        }
    }
#endif
