Does FreeBSD 4.3-release support hardware watchpoint? If so, how to enable
it? I tried something like:

(gdb) watch * 0xc28374d0
Hardware watchpoint 4: * 3263395024
(gdb) watch * (int32_t *) 3263427792
Hardware watchpoint 5: *(int32_t *) 3263427792

But it does not seem to work well. Instead, I have to step through the
code to see when a memory value is changed.

Thanks,

-Zhihui
