IIRC, typing of 'a' and 'n' is enough to avoid the warnings as well. 

In above statement I assumed some interaction between INTEGER actual arguments
to an implicitly typed REAL ABS-function - and REAL-typed arguments to the
implicitly INTEGER-typed MAX-function. Thus, converting all the arguments to
REAL as in

      a(n) = MAX(ABS(2.0),ABS(3.0),REAL(n))

one could think that the warnings should vanish - they don't. So, I concluded,
that it's not related to the argument types.

Btw, adding "REAL ABS,MAX" doesn't help either, so it's not related to the
function's types.

I'll give your patch a try later today.
