Building mac after new headers : Since Mac still does not have 2.0.

Building mac after new headers : Since Mac still does not have 2.0 headers, JOCL compilation fails with 1.x headers of Mac. Removing references to system headers.

The AvailabilityMacros.h are Apple-specific again (they are not contained in the Khronos OpenCL registry. A websearch reveals http://opensource.apple.com//source/CarbonHeaders/CarbonHeaders-18.1/AvailabilityMacros.h , but I'm not sure whether this should be included in the headers directory as well....).

Are they required on Mac? If not, the #include <AvailabilityMacros.h> in cl_ext.h could probably be omitted. If they are required, something like

#include <CL/cl.h>
#ifdef __APPLE__
    #include <AvailabilityMacros.h>
-#endif

would be necessary.

I am also not sure about the right values of the macros here.

Regarding AvailabilityMacros.h : Since this file is already included in CL/cl.h we do not need the include here.. Removed it from the file.

As far as I could test it (on Windows) it worked. Hopefully, it will also work on all relevant versions of MacOS.

Regarding the macro values ... (frankly, whatever AVAILABLE_MAC_OS_X_VERSION_10_7_AND_LATER_BUT_DEPRECATED_IN_MAC_OS_X_VERSION_10_8 means, things seem to be messed up there a bit....) ... I can not say whether they are right or wrong. Maybe I can dig through some of the headers during the weekend, but since it should not be necessary to modify the headers at all, and I can not figure out why it did not compile with the original ones (except for the CL vs. OpenCL path issue), I'm not sure what conclusions I could draw from that...
