The flag was added in the early days for some drivers that had the 
option of being built with 4 byte SQL_WCHAR, it has no particular 64 bit 
platform connection. It should only be used if the application and all 
drivers used are expecting SQL_WCHAR to be 4 bytes in size. And only 
then. So if you don't know you need to use it, I would guess you should 
not set it.
