Perusing thrdvar.h, I see the comment

* Avoid build-specific #ifdefs here, like DEBUGGING. That way,
* we can keep binary compatibility of the curinterp structure */

but later I see precisely

PERLVARI(Twatchaddr, char **, 0)
PERLVAR(Twatchok, char *)

This is a Bad Thing, no? Here's a patch to which gives both normal
and debugging perls the same curinterp structure, at the cost of
saddling all perls with a couple of variables that they may not use.

Setting aside threading #ifdefs, which can't be avoided,
5.005_03 does not have this problem -- although, like _57, it does
have #ifdef OP_IN_REGISTER. But, whatever that is, it's
sufficiently obscure not to matter AFAICT.
