Thanks - I did do some Scheme quite a while ago....

; Remove the .scm extension from c mode.
define-mode c
~with define-submode c
        suffixes '\.\([Cchisyl]\|CC\|cc\|cpp\|gxx\|hxx\)$'
~endwith

the redefinition of c-suffixes is not (usually) needed,
since you can add "before c" to the scheme mode:

; Define a scheme mode for vile.
define-mode scheme
~with define-submode scheme
  suffixes '\.\(scm\|ss\)$'
  before c
        filtername 'vile-lisp-filt -k scheme'
        fence-pairs='()'
        fence-begin='#|'
        fence-end='|#'
        comment-prefix ';'
~endwith

I recall asking Paul Fox long ago about that - I might still have the
related email (but he might remember the answer ;-)
