I know about the package managers, I just wanted to make a point that
AFAIU end-user Posix systems might well lack a compiler.  AFAIR, on
non-free Posix systems, installing a compiler actually costs money.
So having an FFI implementation that requires a compiler might be a
disadvantage on Posix systems as well.

(This is unrelated.)  I don't believe in package managers as a means
to avoid the "DLL hell".  Dependencies are written by people, which
are prone to errors, and having several libFOO.so versions on the same
system, even if their names don't conflict, is not fun.

Not everything, just things no one built, or built in a broken way.
The compiler and Binutils are definitely not my build.

We are talking about the compiler and Binutils.  Building those,
especially the former, is not for the faint at heart, not even on a
Posix host.

It's not that hard, actually, especially if there's no need to run the
configure scripts (as I'd imagine will happen when Emacs supports some
kind of FFI).
