Speaking of gcc-4.2.1, Ted Jordan writes on 20090401:
The generated libtool for building libstdc++ adds the -nostdlib option to the
g++ command for linking but doesn't add -lgcc. This causes a "hidden symbol"
error when linking against the libstdc++ shared object. This patch adds gcc
to the list of libraries linked against when linking libstdc++.

 # Bare metal config options

 config KERNEL_bare_metal

     select BARE_METAL

     help

       'Bare metal' refers to those programs that run without any kernel.

       You probably want to say 'y' here if you plan to use your compiler

       to build bootloaders. It is not yet suitable to build Linux kernels,

       though, because the APCI stuff relies on the target C library headers

       being available?!?!...
