This is worrying to me. I'd really like to know what version of the .NET 
framework you're compiling with, as my best guess is that the problem is 
due to an incompatibility between the version we have in VS.NET 
(1.0.something) and the version of the framework you have.

If your framework version is NEWER than 1.0, this sounds like a change 
MS has made to the C# language since then. Which is slightly odd because 
it's a change which makes the language *less* flexible, by limiting what 
you're allowed to do in a << or >> operator.

I wonder if we can find a log of the "changes from 1.0 to 1.1" anywhere...

The ramifications are, essentially, that a Nint would no longer behave 
exactly like an int when it's placed on the right-hand side of a "<<" or 
">>" operation.

Although this is a fairly rare occurence (I doubt it's used anywhere in 
any code currently) it introduces one more incompatibility between int 
and Nint that I'd like to avoid if possible. If .NET 1.1 enforces that 
rule, though, then that's what we have to do.
