warnings when setting configuration of nodeaccess

Installed on fresh 5.1 drupal system - no previous versions of nodeaccess installed. Box is 2003, php5, mysql 5.018, IIS 6.0. Module goes in with following warnings, and also whenever I set a config of nodeaccess. From what I have seen - only warnings - no errors. nodeaccess appears to be working with setting permissions of nodes just fine.

Not sure what gotcha I may hit later, but thought you could use the info.

Thanks for working on a great module! Hope this info helps you.
Cheers!
