Definitely a cygwin bug; probably related to the removal of d_ino changing
the d_version field of struct dirent from 1 to 2.  Reproducible test case:

$ uname -a
CYGWIN_NT-5.1 LOUNGE 1.5.19s(0.149/4/2) 20051224 14:32:37 i686 Cygwin
$ ./foo
.
..
file1
file2
foo.c
foo.exe
.
..
$ cat foo.c
$ cat ../foo.c
#include <stdio.h>
#include <sys/stat.h>
#include <errno.h>
#include <string.h>
#include <unistd.h>
#include <libgen.h>
#include <dirent.h>

int
main (int argc, char* argv[])
{
  DIR* dir;
  struct dirent* dp;
  dir = opendir(".");
  if (! dir)
    exit(1);
  while ((dp = readdir(dir)) != NULL)
    printf("%s\n", dp->d_name);
  closedir(dir);
  return 0;
}
