question about how to add a machine_func to eu ver. 3.11

I have added a machine_func to ver. 3.11 
 
The actual function resides in execute.e 
and has all the necessary constants in the normal places machine.e, etc.  
 
The function returns an ATOM. 
-- 
global function foo(sequence a, sequence b) 
-- runs some code here 
return my_atom 
end function 
-- 
If I translate the code using ( ec.exe -wat eu.ex ) and run the translated 
interpreter the machine_func works fine with no problems.  
-- 
Then I COMPILE the code after editing be_machine.c and I get this error: 
 
---------------------------------------------------------------- 
compiling the back-end files... 
linking all the files... 
Error! E2028: foo_ is an undefined reference 
file be_machine.obj(C:\1000\SOURCE\be_machine.c): undefined symbol foo_ 
---------------------------------------------------------------- 
 
It appears that I am not decorating the function properly. 
How do I indicate to the compiler that the c code is calling 
a euphoria function in execute.e ?
