No, he certainly meant:

 class A { protected: int prot; acquaintance void Amunger(); ...

I happened to suggest the same in a manuscript just recently submitted
for publication.  In that context, 'acquaintance' just had already
a somewhat weaker meaning, so I proposed 'comrade' -- not in full earnest.

Would something like this suffice:

 class A { int priv; protected: int prot; };
 class Aprot : public A { friend Amunger(); };

Allowing Amunger to access "prot" ?????

(This is stretching my C++ knowledge too far)
