Thank you, sebres, for the homework.

Action taken:

   *   tcl8.6.9 file distribution
   *   Removed anything under pkgs\itcl4.1.2
   *   downloaded ITCL commit [0155e66402] as zip
   *   put the folder contents to pkgs\itcl4.1.2
   *   cd tcl8.6.9\win
   *   nmake -f Makefile.vc
   *   nmake -f Makefile.vc test TESTFLAGS="-verbose bte" > testlog_tcl8.6.9_itcl_0155e66402.txt 2>&1
   *   nmake -f Makefile.vc install
   *   start tclsh, package require Itcl -> 4.1.2

The test failures are fixed, thank you, good work !
