I'm currently testing this build in our CI to see that it does not break anything else. I'd appreciate if you could take the latest version for a spin, particularly a debug build...

@MBaesken, @JoKern65: This seems to break the debug build (fast and slow) on AIX:

jdk/src/java.desktop/share/native/libawt/java2d/pipe/BufferedRenderPipe.c:101:24: error: no member named 'open64' in 'SpanIteratorFuncs'; did you mean 'open'?
    srData = (*pFuncs->open)(env, si);
                       ^~~~
                       open
/usr/include/fcntl.h:115:14: note: expanded from macro 'open'
#define open    open64
                ^
jdk/src/java.desktop/share/native/libawt/java2d/pipe/SpanIterator.h:37:17: note: 'open' declared here
    void     *(*open)(JNIEnv *env, jobject iterator);
                ^

Ah, that has already been reported above. Yeah, interesting that the normal build has passed.
