[Mono-list] ODBC.NET Provider on Windows

[Brian Ritchie]

Guys,

I'm able to duplicate the problem.  The very first call into odbc32 is
failing.  It is a pretty basic call...it only allocates the first handle.
So, it appears to be some sort of interop problem with the dll.  I'm still
checking into it.  Let me know if you have any thoughts.

Brian
