Nothing.  Just use always the UNICODE API, rather than the ANSI API:

  #include <sys/cygwin.h>

  DWORD
  my_GetFileAttributes (const char *cygwin_multibyte_filename)
  {
    DWORD attr = INVALID_FILE_ATTRIBUTES;
    PWCHAR w32_filename = cygwin_create_path (CCP_POSIX_TO_WIN_W,
					      cygwin_multibyte_filename);
    if (w32_filename)
      {
	attr = GetFileAttributes (w32_filename);
	free (w32_filename);
      }
    return attr;
  }
