Akim,
In commit 68ac70bc7bf365fa17bd6d7ea597fa0a05488b8d, in scan-gram.l, I
see this change:
- {directive} {
+ "%"{id}|"%"{notletter}([[:graph:]])+ {
complain_at (*loc, _("invalid directive: %s"), quote (yytext));
}
This has the effect that one must write semantic expressions as
%? { expression }
rather than
%?{ expression }
Was this intentional?
