|
* GIMP_WARNING_API_BREAK:
|
||
|
|
* @message: the message to output either as build WARNING or ERROR.
|
||
|
|
*
|
||
|
|
* Internal macro to use when we consider an API break, so that we don't
|
||
|
|
* forget to look at it when the time comes:
|
||
|
|
*
|
||
|
|
* - When the minor version reaches 99 (e.g. 3.99), the message will be
|
||
|
|
* outputted as a compilation warning.
|
||
|
|
* - When the minor and micro versions are 0.0 (e.g. 4.0.0), the message
|
||
|
|
* will be outputted as compilation error, hence forbidding a major
|
||
|
|
* release unless we resolve all the API break warnings (in any way,
|
||
|
|
* it can be by actually breaking the API, or by deciding that this is
|
||
|
|
* not a valid change anymore).
|
||
|
|
*
|
||
|
|
* Note: this macro relies on the "GCC warning" pragma which was tested
|
||
|
|
* to work on clang too. Assuming/hoping it works on other compilers.
