Re: [Bison-Announce] Bison 3.4.91 released [beta]

[Frank Heckenbach]

Hi Akim,

I can't seem to apply your patches right now (e.g., they have

  -# define YYDPRINTF(Args) do {} while (yyfalse)
  +# define YY_DPRINTF(Args) do {} while (yyfalse)

while 3.4.91 has no such line, only some instances of

  # define YYDPRINTF(Args)

sometimes with a \ at the end), but it's not an urgent issue to me,
so I'll just wait for the next prerelease and test again then. But
don't bother making a prerelease just for that (unless you were
going to release 3.5 otherwise ;).

I agree that cluttering the source would be ugly, but if it's only
in the skeletons, couldn't you do it with m4? (Just an idle thought;
my code requires newer compiler versions anyway, so presuming the
real patch works for me, I'm fine with that and don't really care
what it does with older compilers.)
