If you don't want your code to break when something is deprecated, you
should *always* compile with -d, so no, you don't have to change the
build system if you always have -d. Maybe all needed is just a -di (as
in -wi), where deprecation are informed but not treated as errors.

Scheduled for deprecation makes no sense, it's a user decision to use
deprecated code or not, and if should be a user decision if he/she wants
a warning about deprecated stuff or not.
