-- I think CHARACTER_STORAGE_SIZE and FILE_STORAGE_SIZE have value 8
on all the systems we currently support. For NUMERIC_STORAGE_SIZE,
however, I'm not sure what to do. The standard says "The value of the
default integer scalar constant NUMERIC STORAGE SIZE is the size
expressed in bits of the numeric storage unit (16.4.3.1)." Then
16.4.3.1 says "A nonpointer scalar object of type default integer,
default real, or default logical occupies a single numeric storage
unit". Now the question is:
When the compiler is used with -fdefault-real-8 or -fdefault-integer-8
(but not both), what the heck should the value of NUMERIC_STORAGE_SIZE
be?
