[Bf-committers] CVS Compilation under VS.net 2003

The problem occurs with the lines that reference std::cout.
libcpmtd.lib(xmutex.obj) : error LNK2005: "public: void __thiscall
std::_Mutex::_Lock(void)" (?_Lock@_Mutex@std@@QAEXXZ) already defined in

I figured out a fix for this without commenting out the source:
If you right click on the file SM_Object.cpp and go to properties. Under
C/C++ -> Code Generation -> Runtime Library. Select Multithreaded (/MT)
instead of single threaded.

Interesting that with the same compiler, but compiled from  SCons there
is no problem with Mutex::Lock. AFAICS there is the same libraries in-
and excluded as with the project files.
