PurpleVERSION_MIN_REQUIRED

A macro that should be defined by the user prior to including the purple.h header.

The definition should be one of the predefined Purple version macros: PURPLE_VERSION_3_0, PURPLE_VERSION_3_1, …

This macro defines the earliest version of Purple 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 PURPLE_VERSION_MIN_REQUIRED or earlier will cause warnings (but using functions deprecated in later releases will not).
