local directory setup bug(s)

[David Strobach]

Hi,

In this message http://cygwin.com/ml/cygwin/2003-04/msg01533.html
Rick Kane describes some strange behaviour of setup.exe while installing
from local directory. I have done some testing (debugging) on version
2.340.2.5 and found that:

  a) (WinXP Pro and Win98) searching for source packages in directory
      tree that doesn't contain setup.ini or any .tar.gz files leads
      to crash
  b) (Win98) recursive search for source packages does not work.
        do_local_ini function (ini.cc) returns 0 (ini_count) to
        do_ini_thread, do_ini_thread sets next_dialog to switch property
        sheet back to local dir. selection page and returs to
        do_ini_thread_reflector which posts
        WM_APP_SETUP_INI_DOWNLOAD_COMPLETE message to ThreeBarProgressPage,
        but this message is never hadled/received! Whole setup then looks
        hanged showing progress bar with the Next/Back buttons disabled.
  c) (Win98) finally, if source tree is found, setup crashes while checking
      md5 sums.
