In the last year, some efforts have been made to ensure that the mingw-w64 CRT no longer references symbols that did not exist on XP (e.g. to provide our alternative when there was no `llabs()`). While I didn't test it (I do not have XP installed on any device) it was said to make GNU toolchains produce executables that run on XP. I'd say XP is still sort of 'supported'. However one still has to take care, for example, not pass `%lld` to `printf()`.
