With a proper definition of CHECK_ARCH_EXT (one that always acts like a 
statement without the trailing ';'), the call should be followed by ';'.

And the definitions here should not have the trailing semicolon, because 
that will be provided by the caller.  Also note there should be a space 
between "while" and "(0)".
