It seems that the problems are in four areas:

1) Different Stack cleanup:
   Fairly easy.

2) Different Name Mangling:
   Doesn't Euphoria already depend on the programmer
   using the decorated name?

3) Different double return location:
   Give 2) above, doesn't the C function name
   describe the calling convention?

4) Different structure handling:
   Ditto 3)
