+Summary: We do not report CS0652 warnings (Comparison to integral constant is useless)
+
+Description of Problem:
+We do not report CS0652 warnings (Comparison to integral constant is useless)
+
+Steps to reproduce the problem:
+1. Compile the attached sample with MCS. No error/warning are reported.
+2. Compile the attached sample with CSC. CS0652 is reported.
+
+
+Actual Results (with MCS):
+# mcs cs0652.cs
+Compilation succeeded
+
+Expected Results:
+> csc cs0652.cs
+cs0652.cs(8,7): warning CS0652: Comparison to integral constant is useless;
+the constant is outside the range of type 'byte'
+
+How often does this happen?
+Always
+
+Additional Information:
+CSC knows it's useless but doesn't eliminate the condition from the IL
+generated (even with optimization turned on). Don't know for the JIT.
