Warning C4250 and C4251

Can anyone tell me if it's normal to get C4250 and C4251 warnings ?

Is it safe to ignore them w/ #pragma ?

I compiled CVS head (February 3, 2006) using Ant with the following switchs:

Ant -Dcompiler=msvc -Ddebug=true build

Beside these warnings, trival.cpp provided w/ log4cxx worked fine except
that I had to add the following line just after the #include section: using
namespace log4cxx;
