I compiled the above code with CSCC on my devel install and from the look
of it .. mono does accept the output .. I poked around and found this ...

2002-11-26  Rhys Weatherley  <address@hidden>

        * codegen/ (ILNode_ClassDefn): output a ".size 1"
        declaration in empty "struct" types to match C# requirements
        that a value type can never be zero-sized.

Which fixed some of the issues with running the CSCC compiled binaries
from shared folders .... (someone reported a bug with running those out
of samba shares in Win2k).

Last time someone checked , they did ... Rhys has been all over the 
MS generated binaries with a hex editor and comparing to the ECMA partition
II...  I think it was manyoso who confirmed that the output binaries did 
work on MS .NET...

IIRC, this was reported just after the release of 0.4.8 and is fixed in CVS.
Also the latest 0.5.0 version of does have a fix for this ...

I think this bug needs more thought ... hmm.. 

The difference between insanity and genius is measured by success
