I have a base class Base in a library that defines

public static bool operator ==(Base left, Base right)

In a derived class Derived I define

public static bool operator ==(Derived left, Derived right)

When compiling this with gmcs version or  I get a warning:
/tmp/main.cs(10,28): warning CS0108: `Derived.operator ==(Derived, Derived)'
hides inherited member `My.Library.Base.operator /(My.Library.Base,
My.Library.Base)'. Use the new keyword if hiding was intended
/tmp/library.dll (Location of the symbol related to previous warning)

If I compile both classes into the same assembly I don't get the warning. If I
compile the same code on Windows with csc I don't get warnings either.
