Ah, but there is a "dir.exe" in fileutils on Cygwin.  IOW, the following
worked for me:

$ cat > moises.c
#include <stdlib.h>
main() {
  system("dir");
}
$ make moises
gcc     moises.c   -o moises
$ ./moises
moises.c  moises.exe
$

At a guess, the OP is not using gcc or Cygwin at all.  If so, the question
is off-topic for this list.
