When >you say "a header that will be seen everywhere" do you mean BitVector.h? Or >something more global than that? Again, the advice is general and does not refer specifically to Perl or Perl extensions. "Everywhere" just means everywhere that the tokens in question will be seen by the compiler. For a Perl extension, it might make perfect sense to put it at the top of your XS code as long as the tokens aren't used in any extra C modules that might be included. Data declarations or function prototypes that are shared among C modules are generally placed in a header file, and the redefinition I'm suggesting should be placed wherever those declarations and prototypes are in the package in question.
