Jorgen has maybe already answered your question.  In addition to his
message...

The -1, -2, -3 jazz for cc mode can be explained by this relatively
short snippet from cc-fonts.el:

(defconst c-font-lock-keywords-1 (c-lang-const c-matchers-1 c)
  "Minimal font locking for C mode.
Fontifies only preprocessor directives (in addition to the syntactic
fontification of strings and comments).")

(defconst c-font-lock-keywords-2 (c-lang-const c-matchers-2 c)
  "Fast normal font locking for C mode.
In addition to `c-font-lock-keywords-1', this adds fontification of
keywords, simple types, declarations that are easy to recognize, the
user defined types on `c-font-lock-extra-types', and the doc comment
styles specified by `c-doc-comment-style'.")

(defconst c-font-lock-keywords-3 (c-lang-const c-matchers-3 c)
  "Accurate normal font locking for C mode.
Like `c-font-lock-keywords-2' but detects declarations in a more
accurate way that works in most cases for arbitrary types without the
need for `c-font-lock-extra-types'.")

(defvar c-font-lock-keywords c-font-lock-keywords-3
  "Default expressions to highlight in C mode.")


So not every mode needs 3 choices, there are three choices in cc mode
to suit different tastes.

Cheers.
