But I think this must be fixed in fpc (therefore the clone of the bug),
not in all the packages that build using it.

So, /etc/fpc.cfg should be fixed, no? Can that be done in a MA manner?
If not, I consider the whole fpc/MA design broken.

I disagree. I think a solution where every package needs to define this
is wrong.

The first sentence is what I also thought, but what do you mean by the last?
