The change on line 98 is a correction. In the event a message is received
with severity > 10, the error handler will now be invoked with SYBEMSG.
Previously -- and contrary to the documentation -- the error number passed to
the error handler was the message number.

The sequence of events is unchanged and should be:

1. application invokes db-lib function
2. message received from server
3. message handler invoked
4. error handler invoked
5. data, if any, receieved from the server 6. db-lib function returns

Can't say. Seems like it might.

No. It should be in the nightly snapshot.
