Another issue:

$Config{static_ext} is defined as Win32CORE.  The problem is that any
use of ExtUtils::Embed then requires Win32CORE; its bootstrap call is
included by xsinit and the static library added to ldopts, resulting
in the w32_* functions being exported by any EU::E module.

Where this really breaks things is where a EU::E module is linked with
libtool (as in gnumeric's perl-loader plugin): the xsinit-generated
code calls boot_Win32CORE() but libtool will drop any static link
libraries when creating a shared library/module, meaning the link
fails with an unresolved reference to said function.

AFAICS, static_ext should be empty; packages which actually need the
w32_* symbols can add Win32CORE as an argument to the EU::E functions.
