You're overlooking an important reason to mark functions as extern inline.
That is the case where the author knows that having the functions out
of line will cause the software to not work. I believe this is true in
this instance -- the software is a softmodem and is therefore real-time.
If it makes function calls when the author was expecting it to do two
computations, its performance may well be insufficient to function.
It is better for this program to fail to compile than run too slowly.
