Create a file named MathLibMax and add the source listed below.  When the file is generated, the following exception is thrown:

Caused by: org.eclipse.edt.mof.egl.AmbiguousFunctionReferenceError
	at org.eclipse.edt.mof.egl.impl.QualifiedFunctionInvocationImpl.resolveFunction(QualifiedFunctionInvocationImpl.java:116)
	at org.eclipse.edt.mof.egl.impl.QualifiedFunctionInvocationImpl.getTarget(QualifiedFunctionInvocationImpl.java:49)
	... 87 more

Source:
Program MathLibMax
	function main()
		var1 int;
		MathLib.max(var1/2 - 12, 0);
	end
end

I have fixed this by modifying the algorithm in TypeUtils. The code now attempts to eliminate any function/operation that requires an argument type to be narrowed.

The following test case still have compile errors
------ EGL Source -----------
program testMathlib type BasicProgram {}	
	data any[];
    function main()
    	data.appendElement(1);
        MathLib.max(1, data.getSize() - 50);
    end	
end
