I'd suggest doing this in two steps:

1. move the externs to pyport.h (which is the right place for
   these platform dependent defines and includes) and 
   add #if 0 ... #endif around them

2. check whether these are still needed during the beta phase and 
   if no one complains remove the cruft completely

Alternatively, you could also add specific platform dependent
#ifdefs to pyport.h which only enable the externs on those
platforms where they are needed.
