Yes, we are planning on upgrading the toolchains for JDK 11 and we
usually aim for the latest when we do so. I would say that patches here
are welcome since it will save us work when we finally get around to do it.

Yes, we are certainly interested in exploring WSL as a substitute for
Cygwin at some point. The only reason we haven't started yet is simply
resourcing. Other things have had and still have higher priority.
So far I have only tried building natively in WSL, which works fine for
producing Linux binaries on Windows. Calling the Windows toolchain from
WSL will be trickier. AFAIK, environment variables are still not shared
between the environments, so we must make sure to communicate a good
value for the PATH variable in some smart way for the Windows tools to
work properly. It will also require the source code to be located in a
path reachable from both Windows and WSL and we need to extend fixpath
to handle path conversions. All in all, I expect this to be non trivial
work that will likely require some creative solutions to get to work well.
