In order for a Perl extension module to be as portable as possible

Including this header is the first major one, then using dTHR is all the

appropriate places and using a PL_ prefix to refer to global Perl

variables is the second.

perl -x ppport.h *.c *.h *.xs foo/*.c [etc]

least be acceptable, if not necessarily the most efficient solution, or a
