> What is the meaning for "optional?" for AFP?
We don't have any established process for additional components in the
AFP. The question is, should this go into "$AFP_BASE/etc/components" or not?

Ramana has informed me that the .S file makes some assumptions about
Unix-y behaviour. So it's not surprising to at least one person. Michael
Norrish reported that it works on WSL.

Combined with the other arguments, there seems to be no good reason to
not have it as a component. I'll try to get this done.
