Using #define NDEBUG give me errors in C++

If I define NDEBUG in the top of my main.cpp I get all this errors:

1>  All outputs are up-to-date.
1>libcmt.lib(invarg.obj) : error LNK2005: __initp_misc_invarg already defined in LIBCMTD.lib(invarg.obj)

I'm using MS Visual Studio 2010, boost and gosu libs.

This most likely occurs due to a mismatch between included headers (which will be release version if you define NDEBUG) and linked libraries, which appear to be debug-versions. Maybe some of the headers rely on auto-linking features, and thus you get different versions of a library linked.

This is because MSVC already defines NDEBUG for you in Release build. You shouldn't #define _DEBUG or #define NDEBUG yourself, use the pre-provided #defines.
