porting code that uses NSSocketPort

Hi
I have a command-line app I am trying to port from Mac OS X to  
GNUStep.  It makes extensive use of NSSocketPort.  I'm running into  
troubles, because it appears that the class interface definition for  
NSPort under GNUStep is different than in Cocoa.

In Cocoa, I'm using:

     NSSocketPort *port = [[NSSocketPort alloc] initWithTCPPort:portNo];

However, -initWithTCPPort doesn't seem to be defined in the header  
for NSPort.h on GNUStep (there is a section there which lists this  
method, but it is commented out).

Instead, the NSPort.h header file for GNUStep suggests using:
+ portWithNumber: onHost: forceAddress: listener:

Now, I think I could make this work, but... this seems really  
kludgey, since this particular interface doesn't exist on OSX.   
Therefore, it seems I'd have to start putting a bunch of #ifdefs in  
the code depending on whether compiling for OSX or GNUStep.
Why not just define an -initWithTCPPort for GNUStep's NSPort?

Am I missing something here?

Thanks!
