maybe the cygwin-linker doesn't like object files in MS Win64 object format (generated by ml64).
It doesn't seem to like the whatever the EXPORT keyword is generating... I've attached the patch I mentioned in my original post, in case it's of any use (obviously it breaks everything else as I only touched the Windows assembly). Maybe a def file for jump_fcontext and make_fcontext is a better solution, but how that is done with bjam I don't know. Anyway, with that patch all is well: Performing configuration checks - 32-bit : no - 64-bit : yes - x86 : yes ...patience... ...found 374 targets... ...updating 7 targets...
