I'd rather not say :-) The thing is, if you don't look at the
minibuffer when you're loading files you would probably never notice
it - I've just got into the habit of it I think because I mess around
a bit with ELisp stuff now and again. In fact, the first time I loaded
one of my Ada files I spotted that problem and didn't notice anything
bing screwy with the highlighting!

The problem appears to be in the line (line 1326):

    (if (listp which-func-modes) (add-to-list 'which-func-modes
'ada-mode))

in ada-mode.el. Despite the earlier comment:

;;  This function do not require that we load which-func now.
;;  This can be done by the user if he decides to use which-func-mode

this doesn't seem to be the case! Having looked a bit closer, putting:

(require 'which-func)

before any ada-mode stuff in your .emacs would be adequate without
switching on which-function-mode (you'd obviously lose that nice
feature, but as you never had it anyway...), but switching
which-function-mode on probably does that job anyway.

However I would suggest this is a bug, as changing the above line
from:

(if (listp which-func-modes)
    (add-to-list 'which-func-modes 'ada-mode))

to:

(if (boundp 'which-func-modes)
    (if (listp which-func-modes)
        (add-to-list 'which-func-modes 'ada-mode)))

Appears to work.
