I'd put those things into an include file, and say

(cond-expand
  (chicken (include ...))
  ...)

This requires of course to put the whole definition into the include
file, including the `define'. It is also more portable, because
cond-expand is IIRC not defined for non-toplevel contexts (I can't
check right now, srfi.schemers.org seems to be in a bad mood).
