A directive for Objective-C++ files has been added:

xxx_OBJCC_FILES directive.

Objective-C++ support is relatively new to the GCC compiler for all 
supported platforms (not just MacOS X), so GNUstep hasn't been well 
tested with Objective-C compilers. From what I can work out, some 
headers will need to be modified to compile as Objective-C++ (I've tried 
compiling minimal Objective-C++ code).

You're welcome to make the necessary changes to GNUstep so that it 
compiles with Objective-C++, and contribute them back to the source base.
