It's totally unmaintainable to expect that no global names inside the
backend will ever accidentally match global names in loaded modules.
What we need to be thinking about is why the linker is resolving the name
wrong and how that can be fixed.  I'm inclined to think that this report
indicates a poor choice of link options while building the ODBC library.
