Sorry for the noise.

The syntax for @ is word thanks to c-identifier-syntax-modifications.

It seems to me this regexp in c-basic-matchers-before would never
succeed unless @ is of word syntax.

(concat "\\<"
        (regexp-opt
         '("@interface" "@implementation" "@protocol")
         t)
        "\\>")

Should this patch be applied?
