I understand, however it seems more logical to use the destination type to

Are you completely sure this is the desired behaviour?
It's the behaviour required by the C standard, so yes, it is
absolutely desirable that GCC does that.
The literal 1 has a fixed type and the literal 31 has a fixed type,
and the expression (1<<31) has a fixed type. Whether you assign the
result to a different type does not alter those types involved in the
expression.
Wow, that sounds pretty stupid for a standard again :)
Thanks.
