Boost.config https://www.boost.org/doc/libs/1_75_0/libs/config/doc/html/index.html

is used by all these libraries and  may determine the cxxstd that is supported.

Is now part of Boost. Integer

https://www.boost.org/doc/libs/release/libs/integer/doc/html/index.html

whereas

Are part of Boost.Math
https://www.boost.org/doc/libs/release/libs/math/doc/html/quaternions.html
https://www.boost.org/doc/libs/release/libs/math/doc/html/octonions.html
I believe that the above are quite mature and should still work at C++03.

But many of these below are only tested at C++11 and may fail at C++03 (and others require C++14 or even C++17)

> Math/Special Functions
> Math/Statistical Distributions

These are a useful guide, but the only certain method of determining the actual requirements for a particular program and tool chain is to try it.
