--- Comment #2 from Chengnian Sun <chengniansun at gmail dot com> ---
It seems -pedantic and -Woverflow are different. When I issue 
$ gcc-trunk -c -Woverflow s.c
then there is no overflow warning. (There is indeed no overflow.)

But when I use 
$ gcc-trunk -c -pedantic s.c
the warning says that it is emitted from -Woverflow. Is this expected?
