Wow! Thanks so much for the fast answer. (In my defense: I've read through
the docs, but I haven't connected 'garbage-collection' to this behavior.)
Anyway, I've tried it and it works great for ELF targets but not for COFF
(or PE for that matter). I've read it in the src/ld/NEWS file
that --gc-sections support was implemented for ELF only. Are there plans to
add support for COFF too?

Thanks again,
