Hi!  
I am encountering some weird warnings related to constants while  
using ruby-mysql  
Here are some examples:

c:/ruby/lib/ruby/1.8/mysql.rb:909: warning: already initialized  
constant  
ER\_MIXING\_NOT\_ALLOWED  
There are literally hundreds of exactly similar warnings.

Any ideas?

Thanks and regards,
