Rule Line number for GLR C Parser

[Lars Maier]

Hi,

I was debugging a GLR C parser and noticed that, while for the 
deterministic LR parser the used rules come with line numbers, this is 
not true in non-deterministic mode.


$ diff glr2.c bison-3.4.2/data/skeletons/glr.c
1464c1464
<                   "Reduced stack %lu by rule #%d (line %lu); action 
deferred.  "
---
>                   "Reduced stack %lu by rule #%d; action deferred.  "
1466c1466
<                   (unsigned long) yyk, yyrule - 1, (unsigned long) 
yyrline[yyrule], yynewLRState));
---
>                   (unsigned long) yyk, yyrule - 1, yynewLRState));


This is such a small change but might help others to debug their parsers.
