I'm finding this quite strange for viarious reasons, but g++ also accepts static_cast.
Anyway this project is dead because I'm now retired from professional life and nobody else stepped in durably.

% clang -v
FreeBSD clang version 6.0.0 (tags/RELEASE_600/final 326565) (based on LLVM 6.0.0)
Target: x86_64-unknown-freebsd12.0
Thread model: posix
InstalledDir: /usr/bin

spacegroup.cc:343:36: error: reinterpret_cast from 'nullptr_t' to 'gcu::Transform3d *' is not allowed
        return (i == m_Transforms.end())? reinterpret_cast <Transform3d > (NULL): i;
spacegroup.cc:351:37: error: reinterpret_cast from 'nullptr_t' to 'gcu::Transform3d *' is not allowed
        return (i == m_Transforms.end ())? reinterpret_cast <Transform3d > (NULL): i;
2 errors generated.

Replacing the reinterpret_cast with static_cast makes the build continue without any errors. I'm not sure if this is correct or not due my very very limited c++ knowledge.
