No, I think it's just the usual "don't load subr-x during bootstrap"
problem.  I've now rewritten the offending function.

I think that's fine, so long as the subr-x isn't loaded during
bootstrap.  If I remember correctly.

However, I think it's high time that we put the if-let family of macros
into subr.  However, that doesn't seem to be trivial -- I tried now and
that broke bootstrap, too.
