I hadn't; I have now and it seems to work fine.  I basically assumed there
was some reason I wasn't aware of for putting it in the .rsrc section, so
focused more on trying to figure out how to get binutils to clear the
readonly section flag.  When I couldn't figure that out, I figured I'd ask
here both about the "institutional knowledge" if there was a known reason
why it needed to be in the .rsrc section and because I figured some people
knowledgable in binutils pe stuff might also read this and be able to give
me another idea on making the .rsrc section read/write again if it did
need to stay in that section.
