Additional details

My crate needs to compile C++ source code to an MSVC target, but GUN does not support generating MSVC targets.

our build-servers are linux build servers right now, and there is no way around that. We're using rusts cross-compilation to build the docs for other platforms.

Most crates solve similar issues by using conditional compilation (like a special docs feature that is activated by docs.rs metadata) to exclude the FFI / CPP parts from the compile process. In most cases the docs don't depend on any integration code.
