I don't think so. They've always been there, and they're due to:

63	%token DROP
73	%token ALTER TABLE
74	%token CREATE TABLE
75	%token DROP TABLE

DROP is defined on 63 then defined again on 75. TABLE is defined on 73
then again on 74 and 75. A %token directive with multiple tokens is
exactly equivalent to multiple %token directives.

You can eliminate the warnings with:
