+Subject: [PATCH 1/1] Make c-exp.y work with Bison 3.8+
+
+When using Bison 3.8, we get this error:
+
+    ../../gdb/c-exp.y:3455:1: error: 'void c_print_token(FILE*, int, YYSTYPE)' defined but not used [-Werror=unused-function]
+
+That's because bison 3.8 removed YYPRINT support:
+https://savannah.gnu.org/forum/forum.php?forum_id=10047
+
+Accordingly, this patch only defines that function for Bison < 3.8.
