I on Xenix-286 used other method:

1) Renamed names buffers in neutral names
2) Parsed the code on a maximum quantity of different buffers
3) Also created necessary quantity of buffers in BSS, 
involving macros

Bonus: It is possible to not transfer additional parameters to the
function as the buffer become global, instead of in the stack. 

And the stack on Xenix-286 was strongly limited.
