Yes, but only if you use -W -Wall, which wine unfortunately doesn't :/

bash-3.00$ cat > t.c
int boo(int arg) {
    if (arg);
    return 0;
}
bash-3.00$ /usr/local/gcc-4.0.1/bin/gcc -c -Wall t.c
bash-3.00$ /usr/local/gcc-4.0.1/bin/gcc -c -W -Wall t.c
t.c: In function 'boo':
t.c:2: warning: empty body in an if-statement
