+Make ParseInit and ParseFinalize static to fix -Wmissing-prototypes in
+dtd_grammar.c. Hide ParseFinalize to fix -Wunused-function since this feature
+is not used by Wireshark.
+
+Mark yymajor as _U_ since none of the lemon grammar files seem to use it in
+their %syntax_error directive, this fixes -Wunused-parameter
