  Having just written a "new and improved" dir, I came across the same
behavior.  Fortunately, it only occurs in this one case--using the FA_DIREC
attrib alone.  One way around it would be to make a change like:

  while(findnext(&fileinfo) == 0) /* continue scanning for subdirs */
    if (fileinfo.ff_attrib == FA_DIREC)
      printf("%s\n", fileinfo.ff_name);

One other change you'll be wanting to make in your code:  The result of
getcwd() already ends with \ if you are in the root directory.  So..

  getcwd(path, 250);
  if (path[strlen(path)-1] == '\\')
    strcat(path, "*.*");
  else
    strcat(path, "\\*.*");

Good Luck!
