[Compat build] Warnings persist despite setting compat behavior to false

[Masa-Shin]

The warning message for ATTR_FALSE_VALUE persists even when I set ATTR_FALSE_VALUE: 'false in configureCompat. If I set ATTR_FALSE_VALUE: 'suppress-warning' the warnings disappear, but I would also like to turn off its compat behavior. Is there a way to disable both the warnings and the compat behavior?
