Thats fine, but more generally that linux, you can use a map file to 
instruct the linker what symbols to expose, on some platform it 
optional, on others its required to build a shared lib.

I said that exporting the properties would allow you to use ODBCConfig, 
I never said it would help with connecting via isql. To connect via isql 
it will need to be a ODBC driver exporting the API that isql and the 
driver manager needs. The simple way I find is to add all the entry 
points to the driver, just as stubs. Make each stub print the name of 
the API called, build the lib, and try and connect. See what API calls a 
made, then complete the ones that are needed.
