Hello,

The 9 was just me being sloppy and thinking 9.x, I'm actually using 9.2. These are all the warnings I found in JDK libraries. There are additional ones in other parts of the build which have been dealt with in separate issues.

Hi, Erik.
Why XCode 9 was selected? It seems that 9.2 is the latest one.
9.2 produces some additional warnings even after this fix.

When building with Xcode 9, we get some warnings triggered in jdk libraries. This patch tries to fix them. See bug description for more details on each of them. In short the following things are addressed:

In src/java.desktop/macosx/native/libosxapp/NSApplicationAWT.m, remove the check on MAC_OS_X_VERSION_MAX_ALLOWED. I don't think that's relevant. The source needs to compile against the headers that are present. This was touched on earlier in this thread: http://mail.openjdk.java.net/pipermail/build-dev/2017-July/019486.html and when going back, it's quite clear to me that the fix done there was incorrect.

In src/java.desktop/share/native/libsplashscreen/libpng/pngrutil.c, we can't modify the source file itself, so here I've added a wrapper for zlib.h that rewrites the ZLIB_VERNUM macro to a version that matches what's available on the Macosx version we are building for. This type of override can be brittle but seems to work OK in this case. While doing this, I also refactored the handling of libz cflags and libs. They are better set and exported from configure to be globally available in the build.

We also get warnings when linking static libraries. These are easily fixed by adding the -mmacosx-version-min= arguments on these command lines just like we do for linking shared libraries and executables. I solved this by setting ARFLAGS and actually use that variable.
