Right. It might suffice to put it directly in the .yy file, as later
version do not seem to have yychar.
Whereas later versions do not have yychar, older versions do not have
yyla.type. Putting the above macro into .yy file will fail in at least
one version.
I tried to find a define which allows switches like this:
#ifndef YY_HAS_OWN_YYCHAR
#define yychar yyla.type
#endif
But it seems, there is no macro in bison which could be used as
YY_HAS_OWN_YYCHAR-trigger-thingy. Therefore I think I have to parse the
bison version string :/
