No, looks like this without Win32CORE statically linked in:

========= xsinit.c =========
#include <EXTERN.h>
#include <perl.h>

EXTERN_C void xs_init (pTHX);

EXTERN_C void boot_DynaLoader (pTHX_ CV* cv);

EXTERN_C void
xs_init(pTHX)
{
         char *file = __FILE__;
         dXSUB_SYS;

         /* DynaLoader is a special case */
         newXS("DynaLoader::boot_DynaLoader", boot_DynaLoader, file);
}
========= xsinit.c =========
