Bison 1.28 has our bison.simple rev 1.2 change, but due to code movement, ``cvs'' didn't realize this.
PR: gnu/12868 Submitted by: Vadim Chekan <vadim@gc.lviv.ua> Obtained from: bison-1.26a (identical change was made there)
In case you're wondering, the gcc-2.7.2.1 import uses this to generate code. The size of the generated code is bigger than the entire bison release, making this a saving. The bison doc is pretty good apparently.
