   produce a global definition that can be referenced from the other
   modules.

/* To verify whether ppport.h is needed for your module, and whether any
   special defines should be used, ppport.h can be run through Perl to check
   your source code. Simply say:
   
   	perl -x ppport.h *.c *.h *.xs foo/*.c [etc]
   
   The result will be a list of patches suggesting changes that should at
   least be acceptable, if not necessarily the most efficient solution, or a
   fix for all possible problems. It won't catch where dTHR is needed, and
   doesn't attempt to account for global macro or function definitions,
   nested includes, typemaps, etc.
