While the source requires
```
_ZNKSt8time_putIcSt19ostreambuf_iteratorIcSt11char_traitsIcEEE3putES3_RSt8ios_basecPKSt2tmPKcSB_
std::time_put<char, std::ostreambuf_iterator<char, std::char_traits<char> >
>::put(std::ostreambuf_iterator<char, std::char_traits<char> >, std::ios_base&,
char, std::tm const*, char const*, char const*) const
```
`libstdc++.so.6` only provides
```
_ZNKSt8time_putIcSt19ostreambuf_iteratorIcSt11char_traitsIcEEE3putES3_RSt8ios_basecPK2tmPKcSB_
std::time_put<char, std::ostreambuf_iterator<char, std::char_traits<char> >
>::put(std::ostreambuf_iterator<char, std::char_traits<char> >, std::ios_base&,
char, tm const*, char const*, char const*) const
```
i.e. `tm const *` instead of `std::tm const *`.

A hack along the lines of
```
asm("_ZNKSt8time_putIcSt19ostreambuf_iteratorIcSt11char_traitsIcEEE3putES3_RSt8ios_basecPKSt2tmPKcSB_
=
_ZNKSt8time_putIcSt19ostreambuf_iteratorIcSt11char_traitsIcEEE3putES3_RSt8ios_basecPK2tmPKcSB_");
```
at least allows `clang` to link.
