This is perhaps a case where the casts in C are more portable.

If you write

	* ((volatile long *) some_address) |= some_expression;

it would be quite peculiar (and perhaps even be considered a bug) if the
compiler didn't respect the "long" type and generate the correspondingly
sized load and store instructions.
