  This is the result of a gcc 'feature'.  Currently, if you are going to use 
the shadow headers, you need to compile with -fno-builtin.

  The remaining errors are a result of a bit of a problem in the 
installation; the shadow headers need the shadowing version of libio.h 
installed (the one that #include's bits/wrap_libio.h), but instead get the 
real (non-shadowed) libio.h, since they both live at the same level in the 
include heirachy.

  A temporary solution to this might be to move g++-v3/libio.h to a level 
down in the include search heirarchy (ie gcc-lib/$arch/2.97/include) and copy 
$src_dir/libstdc++-v3/include/c_std/libio.h to g++-v3.
