                                PDO: Support for 'flavour' ODBC driver.
                                include and lib dirs are looked for under 'dir'.
                                
                                'flavour' can be one of:  ibm-db2, unixODBC, generic
                                If ',dir' part is omitted, default for the flavour 
                                you have selected will used. e.g.:
                                
                                  --with-pdo-odbc=unixODBC
                                  
                                will check for unixODBC under /usr/local. You may attempt 
                                to use an otherwise unsupported driver using the "generic" 
                                flavour.  The syntax for generic ODBC support is:
                                
                                  --with-pdo-odbc=generic,dir,libname,ldflags,cflags
