Jo, Thanks for your C expertise. The changes you mentioned were all that was needed to get the MySQLmodule to compile and the MySQLDA to work. I now see the ZMySQL Database Connection in my list of available items in Zope!!! (big smile). I will eventually want to get Andy Dustman's MySQLdb connection to work, because it is multi-threaded. But for now I will stick with what works, learn how to tie Zope to MySQL and THEN go for the upgrade to MySQLdb. Anyway, thanks again for taking the time to solve my problem.
