I didn't mean to say anything like that, not at all.  Mine was a minor
comment, it's supposed to be easy to augment your patch to avoid those
minor issues.  Nothing complicated or fancy is expected, just a
defconst with a value conditioned on system-type.

As for where should that defconst live, I personally have no problem
with its living in python.el for now.  We can always move it later if
the need arises.

Thanks.
