Subject: [PATCH] Generally enable RTTI in the kernel -- by linking against
 libgcc.a we get it for free. Better recompile the complete kernel or you
 might get linker errors when using old objects with missing type_info. For
 the boot loader we'll have to explicitly disable RTTI though -- respective
 commits follow...
