Silly emacs, let's try that again:

  (add-before 'configure 'fix-CPATH
    (lambda _
      ;; Temporary hack to remove -checkout/include which breaks 
      things.
      ;; Why is this not necessary when building in a ‘guix 
      environment’
      ;; and in the Guix linux-libre package? 
      Git-checkout-related?
      (setenv "CPATH" (string-join
                       (cdr (string-split (getenv "CPATH") #\:))
                       ":"))
      #t))

Kind regards,
