It is at least dependency at ECL compilation time (bdwgc requires
it). It isn't that unreasonable to require it for C backend.

@Whimse claims it works just OK for him. I'll have to adjust it to play
nice with cross-compilation framework I'm working on now.

That's what we do - we combine .o files. But Sometimes we want to
combine with already built static libraries. That's when such approach
would be necessary. Mentioned bug affects only such situations. If you
just do monolithic build from lisp lisp sources then there's not a
problem.
