declared after the %merge. * src/reader.c (get_merge_function): Don't set the merger type yet. (record_merge_function_type): New function for setting the merger type and checking for clashes. (grammar_current_rule_merge_set): Set the location of the %merge for the current rule. (packgram): Invoke record_merge_function_type for each rule now that all symbol type declarations have been parsed. * src/reader.h (merger_list.type_declaration_location): New member storing the location of the first %merge from which the type for this merging function was derived. * src/symlist.h (symbol_list.merger_declaration_location): New member storing the location of a rule's %merge, if any. * tests/glr-regression.at (Missed %merge type warnings when LHS type is declared later): New test to catch the error fixed by the above patch.
