This excerpt from java/class.c appears relavant:
void
emit_register_classes (tree *list_p)
{
  if (registered_class == NULL)
    return;

  /* ??? This isn't quite the correct test.  We also have to know
     that the target is using gcc's crtbegin/crtend objects rather
     than the ones that come with the operating system.  */
  if (SUPPORTS_WEAK && targetm.have_named_sections)
    {
#ifdef JCR_SECTION_NAME
      tree t;
      named_section_flags (JCR_SECTION_NAME, SECTION_WRITE);
      assemble_align (POINTER_SIZE);
      for (t = registered_class; t; t = TREE_CHAIN (t))
	assemble_integer (XEXP (DECL_RTL (t), 0),
			  POINTER_SIZE / BITS_PER_UNIT, POINTER_SIZE, 1);
#else
      abort ();
#endif


mingw doesn't currently use crtbegin.o/crtend.o  -- nor any other mechanism to 
init __JCR_LIST__.

I am currently testing a patch (in conjunction with DW2 EH frame support) for 
this but will need about 2-3 days to go through a full bootstrap/reg-test cycle.

A safer option at this stage may be add another condition to disable for 
cygwin/mingw
