Thank you for your initiative.

Creating pull requests for the affected libraries sounds like a good
approach, unless your changes are drastic enough, like changing the
library design or rewriting major parts of it. In the latter case I
would recommend starting a separate discussion thread here for each such
library (don't forget to add the library name tag in the sublect,
similar to how you did in this thread). Library maintainers typically
monitor discussions related to their libraries.

If you end up creating PRs, remember that the changes should be against
the develop branch, not master. We don't make changes to master directly.

Finally, if you're interested in keeping your platform supported, you
might want to consider becoming a tester. This way, at least, the
maintainers (and users) will be able to see the state of Boost on your
platform, and maybe fix the problems as they appear in the future.
