Action blocks may not refer to their own value with number

[Henrik Grubbström]

Found another bug when backporting bison 1.50 kludges:

In bison 1.50 and 1.75 the following construct is no longer accepted:

%union{
  int field;
%}

%type <field> nonterm

%%

nonterm: { $<field>1 = 0; } ;

%%

The following error is produced:

foo.yacc:9.10-20: invalid value: $1

It works fine in bison 1.35.

The obvious workaround is to refer to the value with $$.

Thanks,
