Hi,
I hope this is the right thread to post the observation.
Building recent OpenJDK 9 from sources on Fedora 21 fails with this:
/home/peter/work/hg/jdk9-dev/jdk/src/java.desktop/share/native/libsplashscreen/splashscreen_png.c:
In function 'SplashDecodePng':
/home/peter/work/hg/jdk9-dev/jdk/src/java.desktop/share/native/libsplashscreen/splashscreen_png.c:51:16:

I found that making the following change eliminates the compiler error:

Is this the right way to fix it?
