lint: fix assignment to midrule in grammar (since today) When compiling the grammar with Bison, it complains: error: $$ for the midrule at $2 of 'struct' has no declared type Yacc does not complain, instead it assumes that a midrule has the same type as the rule itself. The assignment '$$ = $1' in the midrule action does not influence the $$ of the whole rule, it only assigns to $2. The assignment to $$ was done via the default action, therefore everything worked as expected. Any missing assignment in this rule would have been caught quickly by the strict assertion in mktag. No functional change.
