Bison now warns when a character literal is not of length one. In
some future release, Bison will report an error instead.
** Verbose error messages fixed for nonassociative tokens.
When %error-verbose is specified, syntax error messages produced by
the generated parser include the unexpected token as well as a list of
expected tokens. Previously, this list erroneously included tokens
that would actually induce a syntax error because conflicts for them
were resolved with %nonassoc. Such tokens are now properly omitted
from the list.
* Changes in version 2.4.2 (????-??-??):
** Detection of GNU M4 1.4.6 or newer during configure is improved.
