+/* This file exists to #include "perl.h" _ONCE_ with
+ * PERL_IN_GLOBALS_C defined. That causes various global varaiables
+ * in perl.h and other files it includes to be _defined_ (and initialized)
+ * rather than just declared.
+ *
+ * There is a #include "perlapi.h" which makes use of the fact
+ * that the object file created from this file will be included by linker
+ * (to resolve global variables). perlapi.h mention various other "API"
+ * functions not used by perl itself, but the functions get
+ * pulled into the perl executable via the refrerence here.
+ *
+ * Two printf() like functions have also found their way here.
+ * Most likely by analogy to the API scheme above (as perl doesn't
+ * use them) but they probably belong elsewhere the obvious place
+ * being in perlio.c
