Well, reading a bit more about it it seems to me that we
1/ use unixOdbc headers to build but at runtime on mac explicitely
load libiodbc.dylib
this is not liekly to end well.
It seems that we _should_ be building forcibly against system-odbc on
Mac... and deal with the conversion UCS4 UCS2 when on 64 bits (or
better based on the size of SQLWCHAR)
