While I'm a big fan of keeping declarations and implementations as close as possible, I find that the need to explicitly #define STB_SOMETHING_IMPLEMENTATION before including the header somehow spoils the simplicity of the solution. At this point, I'd rather use a single file that acts as either a .h or a .c based on __INCLUDE_LEVEL__ (a GCC extension, not sure if available for MSC).
