Hi,

gnu gcc cannot parse some system headers in macOS (10.12)
. One bug is this:

$ cat framework-1.c
#include <Carbon/Carbon.h>
int main(){
 return 0;
}
$ gcc framework-1.c
In file included from /System/Library/Frameworks/CoreGraphics.framework/Headers/CGContext.h:18:0,
                 from /System/Library/Frameworks/CoreGraphics.framework/Headers/CGBitmapContext.h:9,
                 from /System/Library/Frameworks/CoreGraphics.framework/Headers/CoreGraphics.h:11,
                 from /System/Library/Frameworks/ApplicationServices.framework/Headers/ApplicationServices.h:35,
                 from /System/Library/Frameworks/Carbon.framework/Headers/Carbon.h:24,
                 from framework-1.c:1:
/System/Library/Frameworks/CoreGraphics.framework/Headers/CGFont.h:53:1: error:initializer element is not constant
 static const CGFontIndex kCGGlyphMax = kCGFontIndexMax;


The error is issued in gcc/c/c-typeck.c by the following fragment (7 lines):
      else if (require_constant
	       && !initializer_constant_valid_p (inside_init,
						 TREE_TYPE (inside_init)))
	{
	  error_init ("initializer element is not constant");
	  inside_init = error_mark_node;
	}

Is there a workaround that would allow gcc to accept such an initialisation?
