#1 Validate ODBC functionality on Linux

[Michael Lutz]

I'm currently working with a demo ODBC driver from
DataDirect. This needs to be tested. Currently the
code compiles and links properly, and no changes should
be necessary since it works on Windows. But, this
needs to be validated. Note that linking against
different ODBC drivers is driver specific, so the Makefile
is going to have to be adjusted for different drivers.
