[Boost-users] Gregorian 1.32 still has VC71 warnings like 1.31

Do I have some incorrect options here?  I would've thought these would go away, 
but they were the same in 1.31.  I can't find others reporting the same 
warnings.

With this at the beginning of my source:
#include <boost/date_time/gregorian/gregorian.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#include <boost/date_time/date_generators.hpp>

...on VC71, boost 1.32 with all defaults during build of boost, with these 
compiler options:

/Od /I "..\..\..\Vendor\Boost\1_32_0\include\boost-1_32" /I
"..\..\..\Vendor\ace\5_4\dev" /I
"..\..\..\Vendor\Apache\Xerces_C\2_6_0\dev" /I "..\\" /D "WIN32" /D
"_DEBUG" /D "_LIB" /D "_MBCS" /Gm /EHsc /RTC1 /MDd /GS /Fo"Debug/"
/Fd"c:\my_lib\/lib/my_libD.pdb" /W3 /c /Zi /TP .\MyFile.cpp

...and getting these warnings:
