Um, er, right, I think. I am actually surprised that ld managed to get that far into linking the file. That seems to mean that you could make an elf-format object file with all of the right function "linkages" for cygwin and link it on Windows. I know that, these days, binutils can handle multiple different formats by default but I never worked through that this could result in this kind of behavior.
