 Please try to make the emails plain ASCII, for example by attaching
non-ASCII files as attachments, rather than including them in the text body.

One way to try to avoid shift/reduce conflicts is by using operator
precedence (%right, etc.). Look into your .output file at the conflicting
rules, and check what tokens appear immediately after the "." and before
with possibly a grammar variable in between. Then set token precedences on
those tokens. The Bison manual has a calculator example using this.
