I'm playing with the B::C complier backend and am having trouble compiling
the C-code that is produces. I get a bunch of linker error messages like
"[Linker error] undefined reference to `PL_ppaddr'".  The names look like
they might be C functions. Can someone tell where I might find these
functions?

I am running ActiveState perl 5.8.4 on Windows/XP Home.

I originally posted this on the perl-win32-porters list and a subscriber
there, sisyphus, suggested that I also post here. His reply was (in part)

   "However, if I'm not mistaken, the term "undefined reference" indicates
   you're using the gcc compiler, and the ActiveState perl58.lib was built
   with MSVC++ 6.0. You may well find that lib file is incompatible with
gcc."

I am, indeed using the gcc compiler. Here are the first few lines of my
compile log:
