question: is a long line still a problem in current bison version?

[quinte17]

if you have a grammar with many tokens, it can happen that a line gets longer than 16k-bytes.
this is a problem on some compilers, but could get fixed with this "hack".

old output c++ output:
YYASSERT (tok == token::sym1 || tok == token::sym2 || ...) // and many more

new output c++ output:

bool _inlist = false;
if ( tok == token::sym1 ) {
  _inlist = true;
}
if ( tok == token::sym2 ) {
  _inlist = true;
}
... // and many more
YYASSERT (_inlist);

maybe this could get even nicer if using a switch instead of that if...
