What should the order be?  I've already got PerlStub first, and already
see the gazillion warnings about ignoring things in MSL.C.PPC because they
were previously defined in Perl.

I tried moving things around in the link order, and saw no improvements.

Okay.  I'll peruse.

Yeah, I had had to do this to track down a CW error I was getting.  I'm
surprised you didn't see it:  I had to move a goto label outside of an
"if" so that it wasn't empty (it would have a statement near).  Maybe
different versions of CW allow this.

He also has commas after the last element in his structs, which some
people told me gave errors in older versions of CW.

Oh, and while we're on the subject, I made a change to your xsubpp_app
which you might want to roll in:  he includes a "typemap" file in the
module directory which isn't seen by xsubpp_app.  So, below the other
push(@options...) lines, I added

push(@options, '-typemap', "$path:typemap")  if  (-e "$path:typemap");


My question about redirecting stdout earlier was to allow me to script in
the future his method of using perl to generate the header/code files.

Thank you for the work you've put in.  

I want to be confident of my build understanding more than just getting
this module to work.  Gyle Aas is coming out with new versions of
HTML::Parser almost daily!  Sheesh.  I'm envious of his productivity.  In
the time it takes me to figure out just _building_ his module, he's
cranked out nearly a dozen revs.  Better keep drinking my milk.
