I agree that it would be useful, but sadly conditional linkage is just not
supported by the linker script syntax.

Yes, I am beginning to suspect this as well. :-(

If I remember correctly this is because no normal PE section has a VMA of zero.
Or rather the only sections that have a VMA of 0 are debugging sections and
other non-execution related sections. I am a little bit surprised that Windows
did not complain about the .rsrc section having a VMA of 0, but if it likes it
then I am not going to worry.

This would be wrong, I think, as it would cause debugging sections to end up
with non-0 load addresses, which I am pretty sure is a bad thing.
