Fortran, too, unless you do the IMPLICIT trick.

But anyway: Looking at the Emacs modes for Java and C, all keywords like
"private" and "static" (which, similar to "my" in Perl, define scope
rather than type) are in keyword-face.  This would indicate that
keyword-face is to be preferred for the declarators, and type-face for
the types.
