[nas] Multiple defines under Mac OS X

[Jason Lunn]

I am trying to see if I can get NAS to compile under Mac OS X.

So far, porting has been straight forward. I had to add a flag "-Xlinker 
-flat_namespace" to the CC in the makefile so that builds under 10.1. 
Right now, I am sort of stuck, I think. I get the following error during 
make World, and I don't know what to do about it, since it appears that 
both the Xaw and Xt libraries are needed. Any suggestions in resolving 
this?

-Wpointer-arith -traditional-cpp     -L/usr/X11R6/lib

../../../clients/audio/widgets/libwidgets.a -lXaw -lXmu -lXt -lSM -lICE 
-lXpm -lXext -lX11
