Is this series of patches really a good idea?

I realize there's no way to configure GDB at runtime to do this sort of
thing, and I accept that that's a serious shortcoming that we
eventually need to fix.  But you're adding bits to the OpenBSD target
that only make sense in terms of the naming conventions of a single
OpenBSD program (which happens to be the kernel); I've resisted doing
this in the past both for The Server Then Known As XFree86 and for the
Linux kernel.  Why should GDB know the names of functions in a single
one of the infinitely many things it might be debugging?

On a less metaphysical note, I'd worry about any other program with a
function named Xintr.

On a nitpicking note, you missed a space before a parenthesis above :-)
