Not sure what would be going on there.

$ cat try.c
#include <stdio.h>

int main();
void this();

int main(argc,argv)
int argc;
char ** argv;
{
printf("%s\n","Does this work?");
return 0;
}

$ make try
cc "-std=gnu89"    try.c   -o try

$ ./try
Does this work?

$ cat try2.c
#include <stdio.h>

int main();
void this();

int main(argc,argv)
/*int argc;
char ** argv;*/
{
printf("%s\n","Does this work?");
return 0;
}

$ make try2
cc "-std=gnu89"    try2.c   -o try2

$ ./try2
Does this work?
