>How-To-Repeat:


bmake in SDL


>Fix:


Declaration of _XData32 is a little bit confuse:
Solaris Xlibint.h declare _XData32 for LONG64 as :
    extern void _XData32 (Display *dpy, long *data, unsigned long len);

But see the code fragment from Xorg Xlibint.c and Xlibint.h  :
Xlibint.h declare 'int _XData32(..)' but in Xlibint.c _XData32 return nothing.

I am working on a specific patch.

-----------------Xlibint.h------------
ifdef LONG64
#define Data32(dpy, data, len) _XData32(dpy, (long *)data, len)
extern int _XData32(
	     Display *dpy,
	     register long *data,
	     unsigned len
);
extern void _XRead32(
	     Display *dpy,
	     register long *data,
	     long len
);
#else
------------------Xlibint.c-----------------------------------------
#ifdef LONG64
_XData32 (dpy, data, len)
    Display *dpy;
    register long *data;
    unsigned len;
{
    register int *buf;
    register long i;

    while (len) {
	buf = (int *)dpy->bufptr;
	i = dpy->bufmax - (char *)buf;
	if (!i) {
	    _XFlush(dpy);
	    continue;
	}
	if (len < i)
	    i = len;
	dpy->bufptr = (char *)buf + i;
	len -= i;
	i >>= 2;
	while (--i >= 0)
	    *buf++ = *data++;
    }
}
#endif /* LONG64 */
