I'm the main Windows maintainer, and while We've gotten things working
pretty well on Windows, our effort has been 100% on building with msvc
and/or clang-cl. Building with mingw has a different set of pre processor
defines and some other subtle differences, so it doesn't surprise me that
things don't work quite right.

You can try getting lldb-server to build and run under Windows, or you can
try to get it to use the non lldb server codepath on MinGW, but you may
still run into some issues after that as well, since you're the first
person afaik to try building with MinGW
