Well, the following will fix this, but it's rather ugly, and given that the
whole problem can be avoided by just making the "+" character the first
item on the continuation line, it's pretty pointless too! But hey...

(defun f90-match-real-declaration (limit)
 "Match the declaration of a real variable, if this is a single line or 
the first row in a continuation line." 
 (if (or (eq (f90-present-statement-cont) 'single) 
                  (eq (f90-present-statement-cont) 'begin))
                   "^[ \t0-9]*\\(real\\)\\(.*::\\|[ \t]*(.*)\\)?\\([^!\n]*\\)" 
limit t)

And change f90-font-lock-keywords-2 by removing "real" from the regexp that
matches variable declarations, namely "^[ \t0-9]*\\(real||\..., and
inserting the following item after that one:

    (1 font-lock-type-face) (3 font-lock-variable-name-face))
