I'm not sure I understand this argument.
If I used MSAccess to access data from an ODBC source say ORACLE by no strech
of the imagination can I claim that the oracle driver is an extension to MSAccess.
To expand on the point I'm trying to make lets assume I write a C program
that uses commercial MySql ODBC drivers and someother dlls. Do I need to make these
dlls GPL and release their code? The other dlls could even be third party stuff
(MSVCRT.dll!!!).Maybe one of those dlls routes database calls through some shared
library to MySQL ODBC drivers.
Also by that argument any driver manager that was configured to use a MySql
ODBC driver would have to be GPL bcos they make function calls to each other and
definitely share data structures.
