Unfortunately, it doesn't fix.  The byte-compiler still generates
the byte-code which is equivalent to `(funcall 'bbdb-search args)'
in the function `spam-check-bbdb', and then:

(with-temp-buffer
  (insert "From: who\n")
  (condition-case code
      (spam-check-bbdb)
    (error code)))
 => (invalid-function (macro . #[(records &optional name company net...

Since the macro definition of `bbdb-search' should be expanded
before byte-compiling the function `spam-check-bbdb',
bbdb-com.elc should be loaded at the compile time rather than
autoloaded.  The following code will help only BBDB users who
have already installed BBDB.
