Sorry, but I can not reproduce this difficulty at all.
I have compiled today's djgpp CVS tree out-of-the-box
on DOS 6.22, plain DOS 7.10 and in a DOS window on Win98SE
using bsn132b.zip downloaded today from a simtelnet mirror.
The reason for this failure may be that you have downloaded
a broken package.
Unfortunately, I have uploaded a broken package but that package
has never been announced. A day later, after noticing that the
package was broken, I have substituted it with a new one. One or
two days later I have announced this new one. May be you downloaded
a brocken one from your mirror.

Please check the timestamp of some of the products:
bison.exe (2002-01-30 02:03:10)
bison.info (2002-01-30 20:14:58)

Anyway, I would seriously suggest to deinstall the existing bison
on your installation and to install a fresh downloaded one.

Guerrero, Juan Manuel
