Yes, sorry.

Error 216 is a segmentation fault. It looks like a bug in fpmake. I've never
seen this before. I don't know what causes it.

I would get rid of the -Xt and use a proper -XR parameter instead of -Xd.

That script probably hasn't been used for ages. It's probably best to remove it
in order to prevent confusion like you are encountering.

Other than the fact that there are barely any standards on Linux? No.

They might be part of Marco's buildfaq, but I don't know whether it has been
updated already for fpmake.
