Well, dwarf-3 is ok, if it helps to solve the issue. On the other hand
to fake it by secrel32 ref ; .long 0 looks not wrong to me. As PE+
is limited in image size to 2GB there should be any issue about it. A
section relative offset can't get bigger then 2^31 bits.
We could introduce here a .seclrel64 relocation, but wouldn't be
covered by standard.
Cheers,
