Comment (by bdubbs):
* Noteworthy changes in release 3.7.4 (2020-11-14) [stable]
* Bug fixes
* Bug fixes in yacc.c
In Yacc mode, all the tokens are defined twice: once as an enum, and
then
as a macro. YYEMPTY was missing its macro.
* Bug fixes in lalr1.cc
The lalr1.cc skeleton used to emit internal assertions (using YY_ASSERT)
even when the `parse.assert` %define variable is not enabled. It no
longer does.
The private internal macro YY_ASSERT now obeys the `api.prefix` %define
variable.
When there is a very large number of tokens, some assertions could be
long
enough to hit arbitrary limits in Visual C++. They have been rewritten
to
work around this limitation.
* Changes
The YYBISON macro in generated "regular C parsers" (from the "yacc.c"
skeleton) used to be defined to 1. It is now defined to the version of
Bison as an integer (e.g., 30704 for version 3.7.4).
