I don't know. I can only speek for cygwin/mingw on win32.

Really ? I found that data imports are ignored is auto-import is disabled.
static void
pe_find_data_imports (void)
{
struct bfd_link_hash_entry *undef, *sym;

return;

yes, the related linker script moved those definitions to .data too.
The rdata section is completly empty
.rdata BLOCK(__section_alignment__) :

I will try to test it. Unfortunally I cannot find a gcc4 binary for
win32 on the web for mingw/cygwin. Both are still using 3.4.x. Do you
know any additional resource ?
