The test has been in the code for quite a while, I tweaked the test so it
wouldn't create /etc/postinstall/passwd-grp.bat unnecessarily, but even
before that it shouldn't have called mkpasswd or mkgroup if /etc/passwd or
/etc/group respectively already existed.

Are the symlinks Cygwin or Windows style links?  The test looks for the
exact file name and may be sensitive to the extension added to some links in
Windows.  If you haven't already, try re-creating the symbolic links from
the bash prompt.

Give a hobbit a ring and he eats fish for an age.

There is a macro in port.h that maps '_access' to 'access' which I think is
the function defined in src/winsup/cygwin/syscalls.cc.

In src/winsup/cinstall/desktop.cc:
. . .
static int
uexists (const char *path)
{
  String f = cygpath (path);
  int a = _access (f.cstr_oneuse(), 0);
  if (a == 0)
    return 1;
  return 0;
}

static void
make_passwd_group ()
{
  String fname = cygpath ("/etc/postinstall/passwd-grp.bat");
  io_stream::mkpath_p (PATH_TO_FILE, fname);

  if (uexists ("/etc/passwd") && uexists ("/etc/group"))
    return;
. . .
