Hi

As for helping the proting work of #D, i found the not implemented 
class: System.Runtime.InteropServices.RuntimeEnvironment.cs

Find attachted a first version of this class.

I talked with Miguel on IRC about it, and its based on his ideas.
The property: SystemConfigurationFile isnt implemented it. I didn't know 
what path it returns (have to check it at company on a windows box). 
Currently it return String.Empty;

Also the function FromGlobalAccessCache(Assembly a) isnt implemented it. 
It throws a NotImplementedException.

GetSystemVersion() return currently the fixed string: "v1.1.4322"
This seams to be the version string of the .Net 1.1 framework.

The class compiles with the current cvs. Didn't checked it agains 
another version.

If the class is OK for you, someone could please add it to cvs.

Also please add the line: 
'System.Runtime.InteropServices/RuntimeEnvironment.cs'  to the file: 
mcs/class/corlib/unix.args  so the new class gets compiled.

thank you

Regards

Dominik
