The simplest way to go is:

  * build the compiler with '-fnew-abi -fno-honor-std' by saying
  CFLAGS='-fnew-abi -fno-honor-std' CXXFLAGS='-fnew-abi -fno-honor-std' \
       egcs/configure --prefix=$whereever --remaining-options

  gmake bootstrap; gmake install

  * build libstdc++-v3 with the same options

Note: any program linked against libstdc++ should then be compiled
with '-fnew-abi -fno-honor-std'

Hope this helps
