AtkVERSION_MIN_REQUIRED

A macro that should be defined by the user prior to including the atk/atk.h header. The definition should be one of the predefined ATK version macros: ATK_VERSION_2_12, ATK_VERSION_2_14,…

This macro defines the earliest version of ATK that the package is required to be able to compile against.

If the compiler is configured to warn about the use of deprecated functions, then using functions that were deprecated in version ATK_VERSION_MIN_REQUIRED or earlier will cause warnings (but using functions deprecated in later releases will not).
