So you will be happy to note that Bison 3.0 (2013-07-25) announced
that it will move to C99, that 3.1 formally states it

* Noteworthy changes in release 3.1 (2018-08-27) [stable]

** Backward incompatible changes

  Compiling Bison now requires a C99 compiler---as announced during the
  release of Bison 3.0, five years ago.  Generated parsers do not require a
  C99 compiler.

So I agree with 

> it's a good time to shed the accumulated baggage

but, in practice, what exactly are you referring to?
