You can usually just #define vfork fork.  HOWEVER, if they were tricky
about changing variables following the vfork, this may not work.  If all 
they do is exec a different program the #def will be fine.

If they did modify viriables following the vfork, you are out of luck (it
can't be emulated cleanly under Xenix).
