Well the ; is needed in C++ but optional in C.
I was worried about users leaving out the ; by mistake
and not noticing in the normal case of compiling in C.
I suppose one could contrive a change in behavior using something like
if (false)
label: _GL_UNUSED_LABEL puts("true");
That would output "true" always.
Better to give the compile error on C++ rather than that silent gotcha.
thanks,
