[gmx-developers] C++ Address mangling

[Robert McGibbon]

Hi,

When I run them through c++filt, I see

```

$ c++filt _ZN9OpenBabel5OBMol8NextBondERN9__gnu_cxx17__normal_iteratorIPPNS_6OBBondESt6vectorIS4_SaIS4_EEEE
OpenBabel::OBMol::NextBond(__gnu_cxx::__normal_iterator<OpenBabel::OBBond**,
std::vector<OpenBabel::OBBond*, std::allocator<OpenBabel::OBBond*> >
>&)

$ c++filt _ZN9OpenBabel5OBMol8NextBondERN11__gnu_debug14_Safe_iteratorIN9__gnu_cxx17__normal_iteratorIPPNS_6OBBondENSt6__norm6vectorIS6_SaIS6_EEEEENSt7__debug6vectorIS6_SA_EEEE
OpenBabel::OBMol::NextBond(__gnu_debug::_Safe_iterator<__gnu_cxx::__normal_iterator<OpenBabel::OBBond**,
std::__norm::vector<OpenBabel::OBBond*,
std::allocator<OpenBabel::OBBond*> > >,
std::__debug::vector<OpenBabel::OBBond*,
std::allocator<OpenBabel::OBBond*> > >&)

```

Looks like the difference is related to debug symbols, or separate
namespaces being used for debug implementations.
