I just had a look into the sources.  Cygwin's ping is using raw sockets.
This only works for admin accounts, according to MSDN:

  Note  Raw socket support requires administrative privileges. Users running
  Winsock applications that make use of raw sockets must have administrative
  privileges on the computer, otherwise raw socket calls will fail with an
  error code of WSAEACCES.

Use Windows' native ping instead.

The s-bits are just faked.  Cygwin doesn't support switching to another
user context by setting them.  I'm planning to implement that for years
but time goes by...
