-- As required by Fortran standard, stand alone logical allocates same
-- space as integer (but what about the array case???). The convention
-- is important, since in Fortran, Booleans have zero/non-zero semantics
-- for False/True, and the pragma Convention (Fortran) activates the
-- special handling required in this case.
