We want to be able to deprecate macros, but right now the best we can do is to wrap them with things like: #ifndef CLUTTER_DISABLE_DEPRECATED # define A_MACRO_I_WANT_TO_DEPRECATE ... #endif Which requires adding a new symbol to the build, and will cause a build error instead of a compiler/pre-processor warning. Fortunately, we can use the _Pragma() keyword introduced by C99 and supported by GCC to add a warning to the output, while leaving the macro itself intact. GCC does not have a "deprecated" pragma, so we have to use a generic warning; this also means we cannot do nifty things like concatenating strings and the like, as we do for the "deprecated" attribute. The macro deprecation symbol should have the same affordances as the function deprecation one, and evaluate to nothing if the required version is lower than the current version; or if the global toggle for deprecation warnings is in effect.
