I discovered a difference in behavior of bison 1.35 and bison 1.870.
In the file xkbcomp.y of the xfree86-4.2.1 release, there is a rule
that looks like the following in lines 422 and 515:
nonterm : rhs1 { action1 } | rhs2 { action2 } ; | rhs3 { action3 } ;
1.35 either ignores the first semicolon or generates wrong code,
but 1.870 flags that as an error, which should be the correct behavior.
To get xfree-4.2.1 to compile successfully, I just removed those
offending semicolons. Also I decided to replace bison-1.35 with
bison-1.870. By the way, 1.870 does not have the template files
bison.simple and bison.hairy anymore.
