Done. I preferred to use locate-file instead of executable-find,
since the latter would load another package.
The new version is below, in case someone wants to comment.
(defcustom c-macro-preprocessor

'("/") exec-suffixes 'file-executable-p)
"/usr/ccs/lib/cpp -C")
((locate-file "/lib/cpp"

"/lib/cpp -C")
;; On some systems, we cannot rely on standard directories to

((locate-file "cpp" exec-path exec-suffixes 'file-executable-p)
"cpp -C")
(t "gcc -E -C -o - -"))
"The preprocessor used by the cmacexp package.

option, or to set an equivalent one."
