I am not sure if this is a problem with the patch or with ia64 HP-UX but
I am getting a build failure:
/proj/opensrc_nobackup/nightly2/build-ia64-hp-hpux11.23-trunk/obj_gcc/ia64-hp-hpux11.23/libstdc++-v3/include/tr1_impl/complex: In function 'typename __gnu_cxx::__promote<_Tp>::__type std::arg(_Tp)':
/proj/opensrc_nobackup/nightly2/build-ia64-hp-hpux11.23-trunk/obj_gcc/ia64-hp-hpux11.23/libstdc++-v3/include/tr1_impl/complex:314:14: error: 'signbit' is not a member of 'std'
I will try to investigate this and get more details about the failure.
