Windows SheepShaver CVS doesn't build-(dyngen)

[dmbtech]

./dyngen.exe -o basic-dyngen-ops.hpp obj/basic-dyngen-ops.o
dyngen: ret or jmp expected at the end of helper_op_invoke

Thats result of compiling on windows platform for cvs right now. I can't figure out how to fix that proble, in fact that hpp file has some assembly in it, which i don't understand. Anyone know whats up with that? once that is fixed, ill be able to have weekly builds of Sheepshaver on windows and linux.
