in thread DBI fails to return an error code

It was a bug but I don't think you are totally out of the woods yet. See post to the perl@lists.mysql.com list from Ralf Neubauer at DBD::mysql: no errstr under Windows.

It may well be worth you subscribing to that list. BTW, you can see diffs between different versions of CPAN modules from CPAN tools e.g., http://search.cpan.org/tools/DBD-mysql-4.020
