It would be a new software, the source of the original software being like a 
set of specifications. Take Java for example: there's free implementations 
even if the ones from Sun and IBM are proprietary. In the case of your fct 
external, you read the FORTRAN routine, you understood it and you rewrote 
it in C with an interface for PD. The ACM licence does not say you must 
release your new software with the same license, it says that you must 
identify what comes from the original code and attribute it to the ACM.
