I'd suggest marking them strict in the function declarations. Some attention to volatility declarations (isCachable or isImmutable) would be a good idea too. Also, it'd be faster and more portable to write the functions with version-1 calling conventions. Using the Makefile to auto-create the differently sized versions is a slick trick... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
