I thought what I wrote was the reason. But if you think it's not a
reason, or that it's not important enough, by all means go ahead and
commit the changes; that's why I said ``perhaps'' in my last sentence.
In case my wording wasn't clear: adding yet another subtly
incompatible watchpoint implementation for ia32 target might be
largely a wasted effort, since they all will have to be revisited
when/if the generalized code is finished and accepted.
