Hi,

    Bug : https://bugs.openjdk.java.net/browse/JDK-8074829
    This bug is to remove warning suppressions from makefile and fix the warnings for libawt_headless library.    

    I have removed following warning suppressions & fixed the warnings for libawt_headless library.
    DISABLED_WARNINGS_gcc := maybe-uninitialized int-to-pointer-cast 
    DISABLED_WARNINGS_solstudio := E_DECLARATION_IN_CODE

    Warning suppression that cannot be removed :
    DISABLED_WARNINGS_solstudio := E_EMPTY_TRANSLATION_UNIT
    This is due to the fact that - jdk/src/java.desktop/share/native/common/java2d/opengl/OGLBlitLoops.c file becomes empty file in case of HEADLESS mode compilation.


    I have run the JPRT build on this fix. It built successfully on all platforms - please see :
    http://scaaa637.us.oracle.com/archive/2016/04/2016-04-20-071524.ajit.client/JobStatus.txt
    Also, I have built it on Windows 7 with Visual Studio 10.
