  Issue 1793: Add ctypes.util.find_msvcrt() function (on Windows).
........
  r63396 | thomas.heller | 2008-05-16 22:19:07 +0200 (Fr, 16 Mai 2008) | 4 lines
  
  Very simple test for ctypes.util.find_library on Windows.
........
  r63511 | thomas.heller | 2008-05-20 21:53:47 +0200 (Di, 20 Mai 2008) | 6 lines
  
  On HPUX, -fPIC must be used for linking.  _ctypes now builds on HP-UX
  IA64 and PA machines.
  
  The ctypes unittests work fine on the IA64, but dump core in
  test_qsort on the PA.
........
  r63522 | thomas.heller | 2008-05-21 20:47:02 +0200 (Mi, 21 Mai 2008) | 2 lines
  
  The -x <test1[,test2...]> flag allows to exclude tests.
........
  r63523 | thomas.heller | 2008-05-21 21:47:44 +0200 (Mi, 21 Mai 2008) | 2 lines
  
  Oops, get_tests may be called with 3 arguments.
