<pre>Since the C standard does not explicit says that this is not allowed it would
be better if Clang simply issue a warning when building the following code:
#include <stdio.h>
#include <stdlib.h>
int main(int this, int that, int another) {
return 0;
}
With GCC:
$ gcc -c main.c -o main.o
OK
With Clang:
$ clang -c main.c -o main.o
main.c:4:5: error: second parameter of 'main' (argument array) must be of type
'char **'
int main(int this, int that, int another) {
^
main.c:4:5: error: third parameter of 'main' (environment) must be of type
'char **'
2 errors generated.</pre>
