You can use `fboundp' like so:

   (if (not (fboundp 'malloc)) (load-file "c-utils.elc"))

although provide/require might be better.  To use that, stick:

   (provide 'c-utils)

in the beginning of the c-utils.el[c] file, and:

   (require 'c-utils)

in place of your 'if' test; it replaces the whole test, not just the
`if' predicate.  Note that "c-utils.elc" must now be in your load-path
(set with EMACSLOADPATH environment variable or `set[q]').  If not, you
can cheat, and say:

  (require 'c-utils "/usr/you/very/long/path/c-utils.elc")

See doc-strings on these functions for details.  Your mileage may
vary.  :-)
