Beta 18 bash will complain if /tmp is missing

Yeah, this should be done.  I just added the following at the beginning of
main() in bash/shell.c which seems to do the trick:

#ifdef __CYGWIN32__
  /* verify that /tmp exists, complain if it doesn't */
  {
    struct stat statbuf;
    if (stat ("/tmp", &statbuf) < 0)
      {
        printf("WARNING: bash couldn't find /tmp, please create one!\n");
      } 
    else /* stat succeeded */
      {
        if (!S_ISDIR (statbuf.st_mode))
          printf("WARNING: bash needs /tmp to be a valid directory!\n");
      }
  }
#endif __CYGWIN32__
