Perhaps cond-expand could be extended.  Maybe `guile-foo' feature to
mean one of guile's features list.

That should be ok though.  A good compiler will want to recognise and
optimize things like that, and drop resulting dead code.

(Gratuitous plug: in my guile-lint I look for a few forms like that,
to suppress warnings in code that's intended for particular guile or
module versions.)
