Can you compile a header to an object file so that its definitions don't have to be recompiled every time the including file is recompiled?

Eh... Yes?

GCC [0], Clang [1] and others [2] have supported for compiled headers. Cmake also has support for precompiled headers [3].

I would say both the tool and architecture to do that is well supported.
