$ cat argv.c
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

int
main(int argc, char *argv[])
{
    printf("argv[0]: %s\n", argv[0]);

    if (open(argv[0], O_RDONLY|O_BINARY) < 0)
        perror("open");

    return 0;
}

$ gcc -o argv.exe -g -O2 argv.c

$ ./argv
argv[0]: ./argv
open: No such file or directory

$ ./argv.exe
argv[0]: ./argv
open: No such file or directory

Is this expected behavior?  Thanks.
