--- Comment #3 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
Thanks.  The next errors are:

/homes/botcazou/gcc-head/src/libcody/client.cc: In function 'Cody::Packet
Cody::ConnectResponse(std::vector<std::basic_string<char> >&)':
/homes/botcazou/gcc-head/src/libcody/client.cc:217:64: error: 'strtoul' was=
 not
declared in this scope
       unsigned long val =3D strtoul (words[1].c_str (), &eptr, 10);
                                                                ^
mv -f .deps/libz_a-trees.Tpo .deps/libz_a-trees.Po

   unsigned long val =3D strtoul (str.c_str (), &eptr, 10);

and are fixed by adding

#include <cstdlib>

to both files.=
