> Joel, could you test the #ifndef version and check it in?
I verified that the attached patch allows gdbserver to build,
and I also double-checked the values with the ones I have in
my prctl.h file. But I've never used gdbserver before, and when
I tried it, I had a failure:
(gdb) target remote localhost:2345
Remote debugging using localhost:2345
Couldn't establish connection to remote target
Remote register badly formatted: T0506:0000000000000000;07:c0f1ffbf7f000000;10:2
06f55952a000000;
here: 0000000;07:c0f1ffbf7f000000;10:206f55952a000000;
Not sure why there seems to be discrepancy in the protocol...
In any case, I checked in this patch, since it can only be correct.
