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.
