Comment 2 Miro Hrončok 2021-01-29 15:56:24 UTC 
'#pragma message: CAUTION: Boost.Geometry in Boost 1.73 deprecates support for C++03 and will require C++14 from Boost 1.75 onwards.'

That was it. But I was confused by how is this told. I'd expect it to error out with:

Boost.Geometry in Boost 1.75 onwards requires C++14.
Comment 3 Miro Hrončok 2021-01-29 15:58:54 UTC 
Scratchbuild with C++14:

https://koji.fedoraproject.org/koji/taskinfo?taskID=60826155


A local mockbuild on x6_64 passed, so I assume this will as well.
