[CMake] Windows GCC 4.4 with shared libstdc++

[Gregory Peele ARA/CFD]

Hey all,

I recently downloaded MinGW GCC 4.4 and have been toying around with it.  I've been trying to get the shared libstdc++ support working under CMake 2.6.3.  Anyone ever tried this before?  Currently I'm having two issues - multiply defined symbols coming from libstdc++.a and libstdc++_s.a (presumably because the compiler is implicitly linking to the first and I'm also specifying linking to the second) and undefined references to std::exception default constructor.  

According to MinGW documentation, only thing that should be necessary is adding -D_GLIBCXX_DLL for all input files and linking against libstdc++_s.a.  The same project builds correctly when built with static libstdc++.  Any thoughts?
