Thanks for your answers,
Indeed, if I copy the m4 macros from a fresh gnulib, it works. So a bootstrap 
to get a
recent gnulib would probably solve it.

However, that is exactly what I don't want to do. Newer versions of gnulib have 
numerous
issues in Interix, not to mention any possible problems that would arise using 
a newer
version of gnulib in a release package. Besides, there is no bootstrap script 
in the bison
2.3 package.

aclocal.m4 is replaced by autoreconf. I deleted the cache - no effect.

Any other workaround?
