By the way, this isn't the best way to handle MySQL++ errors.  In this 
instance, what perror appends to your string will only be correct if the 
connection failure is due to an error return from a system call.  If 
something else goes wrong, such as the server rejecting your login 
parameters, it will tell you something like "no error" because the last 
system call to run probably succeeded.

Far better is to either a) enable exceptions, getting the error message 
from the exception object; or b) call either Query::error() or 
Connection::error() (same thing) to get the error message.
