Re: [PATCH] lib/rename.c: Conditionally define the out label

[Paul Eggert]

Another argument for omitting the semicolon is, suppose we add another 
label-related attribute later?  _GL_HOT, say?  Then, 'lab: _GL_HOT 
_GL_UNUSED_LABEL' would work, but 'lab: _GL_UNUSED_LABEL _GL_HOT' would 
not, and users would have to remember to always put _GL_UNUSED_LABEL 
last among all the other label-related _GL_whatever attributes; that 
wouldn't be good.
