+| | |
+| | | phase 1 of somewhat major rearrangement of PERL_OBJECT stuff
+| | | (objpp.h is gone, embed.pl now does some of that); objXSUB.h
+| | | should soon be automated also; the global variables that
+| | | escaped the PL_foo conversion are now reined in; renamed
+| | | MAGIC in regcomp.h to REG_MAGIC to avoid collision with the
+| | | type of same name; duplicated lists of pp_things in various
+| | | places is now gone; result has only been tested on win32
