These look relevant:

  $ perl -V:libperl
  libperl='libperl520.a';

  $ perl -V:so
  so='dll';

(The latter because the extension we build -- when we succeed to build
it -- will have the .dll extension, not the .so extension as on Unix.)

Not sure what you mean by "get an ExtUtils::MakeMaker makefile
working".  I already have ExtUtils installed, and the files you
mention are present.  But what should I do with them?
