Dear maintainer,
I bet you already know that Bison... 2.7 up to... 3.1 I think?
Can output a PREFIX.tab.c doc so that when compiled by
LLVM 9 a security warning (see `man 3 printf`) gets
emitted.
I don't know much about LLVM, but I think they claim to be
GCC compatible. Does Bison in any way claim
of this will be enough compliant with your etiquette
(which I'm not familiar with), and in any case you already have (if
that helps) an open source not reduced example.
Thank you. Truly best cheers and regards!

Oh, sorry. Code written by me in the action of a production rule

Hi,
if you happen to use GNU Bison from Apple Xcode, I got a
question for you:
How would you detect Xcode from GNU Make?
I would want to run `sed 's/#line/\/\/#line/'` on the generated parser
in order for it not to show as assembly during debugging. I think
Xcode has some kind of non honoring to
lly yet,
for it to remove the _line_ preprocessor directives.
Also I haven't figured out yet how to configure that Make target as
a build step before the program target itself.

However, if Bison could react to some rule reconfiguring the way it sorts
precedences, I would find that rather interesting.

Please forgive me this little off-topic: I'm having the same alert in

Well... for flex 2.6.4 goes away when replacing `%option noyywrap` for
a real `int _wrap(void) { return 1; }`. So that’s an easy workaround
if those warnings where blockers. But I think the `%option` should prevent
such thing from popping up.

Hey,
can’t remember any such graphviz failure, even with graphs
so large, their output isn't actually useful, unless for navigating
with e.g. xdot.
I however have only used -Tpng, never -Tpdf. Also no -O, but I
guess that’s simply and works the same for all cases.
