Which means a practical library might have to contain 2 copys of a given 
function if your code is not arranged in the same order as the library. 
I believe the trig.l is an example of that out of order, so I think if 
you look at it you'll find more than one copy of one or 2 modules in 
that library.

os9gen doesn't work with c modules.
