+Summary: String Compare on InvariantCulture should not be ordinal.
+
+Currently in Mono we assume that `InvariantCulture' string compares
+means `ordinal' compares, as shown by this test on the class libs:
+
+The followin program should print "ok":
+
+using System.Globalization;
+using System.Collections;
+using System;
+
+
+class D {
+	public static void Main ()
+	{
+		int t1 = CultureInfo.InvariantCulture.CompareInfo.Compare ("a", "A", 0);
+		int t2 = CultureInfo.InvariantCulture.CompareInfo.Compare ("a", "A",
+CompareOptions.Ordinal);
+		
+		Console.WriteLine ("Must be < 0 = " + t1);
+		Console.WriteLine ("Must be > 0 = " + t2);
+
+		if (t1 >= 0 || t2 <= 0)
+			Console.WriteLine ("Failed");
+		else
+			Console.WriteLine ("Ok");
+	}
+}
+
+
+This bug can be seen in our regression test suite for mscorlib in
+Collections/ComparerTest/Invariant.
+
+The problem seems to be the code in locales.c, in the routine:
+string_invariant_compare_char.
+
+A FIXME comment is there, we need to find out the rules for ordering
+even for the InvariantCulture
