[KOS] [PATCH] get Boost shared_ptr etc. working

[Jim U. <ji...@3e...>]

I got Boost shared_ptrs working, and probably other parts of Boost that
are header-file only.  You need to do the following:

1. Enable SGI iostreams in STLport (without compiling the library).
This pulls in the iostream declarations; the linker won't complain unless you  
call or actually instantiate an iostream function.

2. Also #define _STLP_NO_CWCHAR in stl_user_config.h.

3. Patch KOS with the attached patch.  It makes calls to typeid()
assert at runtime.  (Normally compilation errors will occur instead
when RTTI is disabled.)  You can #define __RTTI before compiling
libk++ to leave the stub typeinfo functions out.

4. Add the boost path and libk++/include to your include path.
It is not necessary to compile Boost; in fact I doubt it will work.

5. #include <rtti.h> before any inclusion of boost header files.
This file simply redirects typeid(X) to typeid_override().

A short test program is attached as well.
