Hi,
As I understand it, the point of having "do {} while (0)" in a
multi-statement macro is to turn it into a simple statement. As such,
ending with a semicolon in both the macro definition and the
invocation will turn it back into multiple statements, creating
confusion if someone were to invoke the macro in an "if" statement.
Even if that never happens, it seems good to keep them all consistent,
as in the attached patch.
