Marcus,

These two methods are not part of the OpenStep spec.   Since we are, however,
going for compatibility w/ MOSX I would recommend that they be implemented.
GNUSTEP_HOST_CPU returns the architechture, not the OS.  I believe you meant
GNUSTEP_HOST_OS.  Even that, however, may not be sufficient...

If you look at:

http://developer.apple.com/techpubs/macosx/Cocoa/Reference/Foundation/ObjC_classic/Classes/NSProcessInfo.html

You'll see that the operatingSystem method you mention returns one of the
following constants:

NSHPUXOperatingSystem 
NSMACHOperatingSystem 
NSOSF1OperatingSystem 
NSSolarisOperatingSystem  
NSSunOSOperatingSystem 
NSWindows95OperatingSystem 
NSWindowsNTOperatingSystem

The operatingSystemName method returns a string corresponding to one of the
above.  For Linux we will likely need to add a GNUstep specific constant. 
Probably something like "GSLinuxOperatingSystem".   We can, of course, use the
value returned by GNUSTEP_HOST_OS to determine which of these constants to
select.
