1663	build.bat cannot set/reset ERRORLEVEL	Takeshi Mouri <takeshi.mouri.net@…>	René Rivera	"The file build.bat says
  REM NOTE: The ""setlocal & endlocal"" construct is used to reset the errorlevel to 0.
But this does't work on Windows 2000/XP/Vista.
And says aloso
  REM NOTE: The ""set _error_="" construct is used to set the errorlevel to 1
This does't work on Windows Vista.

So, my Proposed resolution is

 reset the errorlevel to 0::
   ver>NUL
 set the errorlevel to 1::
   dir NUL>NUL 2>&1"	Bugs	closed	Boost.Jam 3.1.17	bjam	Boost.Jam 3.1.16	Problem	fixed
