And I think GCC is wrong to wan here. The point of the Wempty-body
warning is to catch things like:
if(a);
return 2;
return 3;
However,
if(a)
;
return 2;
seems intentional. Clang++ does not warn on the latter and it prints
for the former:
warning: if statement has empty body [-Wempty-body]
if(a);
^
note: put the semicolon on a separate line to silence this warning
which seems a nice way to silence the warning instead of ugly { ; }
Cheers,
Manuel.
