+Subject: Adapt to Bison 3.8 internal yyn -> yyrule rename
+
+see
+<https://git.savannah.gnu.org/cgit/bison.git/commit/?id=f30067ed51f23802fc91761ede1506dfa72b2865>
+"glr2.cc: log the execution of deferred actions" including "Rename argument yyn
+as yyrule for clarity."
+
+YYBISON was defined as 1 rather than as a representation of the Bison version
+prior to
+<https://git.savannah.gnu.org/cgit/bison.git/commit/?id=21c147b6e5372563b7c4741deadaddb9354f4b09>
+"yacc.c: provide the Bison version as an integral macro", which shouldn't be a
+problem here.  And YYBISON is apparently completely undefined with
+/usr/bin/bison on macOS.
+
+(The preceding comment always mentioned "yyi" and "yyrmap" in apparent mismatch
+with the actually used "yyn" and "yyr1" ever since
+c25ec0608a167bcf1d891043f02273761c351701 "initial import", so just leave it
+untouched.)
