[Mono-list] mcs won't allow implementation of interfaces withstatic methods

[Jeroen Frijters]

I disagree, while C# doesn't allow static interface declarations, that
doesn't mean C# should be unable to implement interfaces from other
languages that do add static methods to interfaces. There is nothing in
the C# language specification that forbids that. You don't support
static methods in interfaces, so just ignore them. Besides, the current
error message is incorrect, fixing the compiler is less effort than
fixing the error message ;-)

On the Rotor list where this was also discussed (I posted this issue
there and here), it was suggested that MS would fix the C# compiler (by
making it ignore all static methods in interfaces).

Jeroen
