It's not a bug, it's a feature!  :-)

mcs implements most of the C# 2.0 features except for Generics (which
are in gmcs).  The "bug" you're seeing is a C# 2.0 feature, type
inferencing and implicit delegate conversion.

If you need to target C# 1.1 for .NET compatibility, add the
-langversion:ISO-1 argument to your mcs command line.
