svn(1) diff against the ports tree
LLVM9 has made it to head/, so mongodb36 does not currently build on head. Attaching a patch (against the ports tree) that backports the upstream fix: https://github.com/mongodb/mongo/commit/9c6751b9765d269b667324bb2efe1ca76a916d20 -- it should be noted that llvm now warns because this is a C++17 feature, but it builds it anyways.
Many thanks, Kyle.

Yup... I'm doing a bit more testing on older FreeBSD versions (with older clang) and looking to get this tested w/ GCC just to make sure that it doesn't regress anywhere, then I'll poke someone for commit.
