Yep, that's what I thought.  Glad I got it right, saved another
re-roll :-)

And as an aside, if we'd somehow got '_PATH' to be a defined macro,
I say that something would be very, very wrong with the current setup
(Autoconf strives to be very namespace-clean these days, apart from
some old m4 builtins, which must remain available out of the 'm4_'
and 'AC_' namespaces for sake of backward-compatibility).

Today, excluding few exceptions, I'd say that the main reason to
properly quote macro arguments is to avoid commas or quoting characters
in macro invocations or expansion, or even quoting characters themselves,
to be spuriously considered as metacharacters and thus processed.
