 	* convert.cs (UserDefinedConversion): Call UserDefinedConversion
 	recursively to find all possible conversions, because a UserCast
 	might be necessary to cast original_source into most_specific_source.

+Hohum, so I reread the bug report.
+
+My patch works if I keep:
+      SuperDecimal sd = i;
+
+polysemy:~/bugs $ mcs 68711.cs
+ImplicitConversionStandard from Int32 to SuperDecimal
+ImplicitConversionStandard from Int32 to Decimal
+ImplicitConversionStandard from Int32 to Int32
+68711.cs(18) warning CS0219: The variable 'sd' is assigned but its
+value is never used
+Compilation succeeded - 1 warning(s)
+
+If I change that to:
+      SuperDecimal sd = (SuperDecimal) i;
+
+I get:
+polysemy:~/bugs $ mcs 68711.cs
+ImplicitConversionStandard: from Int32 to SuperDecimal
+ImplicitConversionStandard: from Int32 to Decimal
+ImplicitConversionStandard: from Int32 to Decimal
+68711.cs(18) error CS0030: Cannot convert type 'int' to 'decimal'
+ImplicitConversionStandard: from Int32 to Int32
+Compilation failed: 1 error(s), 0 warnings
+
+So It does work eventually, but I need to supress that CS0030 error in
+this case.
