Compile Warnings with v110

[Hoikas]

When compiling with Visual C++ 2012 (v110 toolchain), I see many compile warnings (almost ten thousand) of the same type. They seem to all occur when using a libhsplasma DLL_[CLASS|STRUCT] in an STL container.

C:\Development\Plasma\libhsplasma\core\Util/hsBitVector.h(77): warning C4251: 'hsBitVector::fBitNames' : class 'std::map<_Kty,_Ty>' needs to have dll-interface to be used by clients of class 'hsBitVector'

I have no idea what these warnings mean (they weren't present with v100). I do know that they seem to be increasing the compile time, which is somewhat frustrating.

EDIT: According to MSDN (http://msdn.microsoft.com/en-us/library/esew7y1w.aspx), they're garbage in this case. Can we disable these?

Actually they've been there since at least VS2008 (maybe earlier) -- I tend to disable that warning, since the last time I checked there was nothing (sane) that could be done about it.

I guess VS11 has increased the default warning verbosity :(
