Grrr, I knew I should've read the man page. I guess you can't expect to
get _all_ warnings when specifying -Wall
*sigh*

% cc -std=c99 -O -pedantic -Wall -Wshadow -Wuninitialized test.c
test.c: In function `main':
test.c:8: warning: declaration of 'i' shadows a previous local
test.c:7: warning: shadowed declaration is here
test.c:7: warning: 'i' might be used uninitialized in this function
