To express it more clearly, RM 2.2(14) requires implementations to
support lines and lexical elements of /at least/ 200 characters, but
/allows/ implementations to support longer lines and lexical elements.
I'm not sure if GNAT supports more than 200 characters, though. And of
course an Ada program that uses more than 200 characters may not be
portable to compilers that support only 200.
But I don't see any direct logical connection to the number of digits
that Big_Integers can support. While one cannot write a big-number
literal longer than a line or longer than the maximum length of a
lexical element, that should not directly limit the size of big-number
values in computations.
