For MSVC, assuming that you have the proper dependencies for JIT
compilation and LLVM available, and just for the reference if anybody
is interesting in making that happen (Tom and Andres are aware of that
already), one would need to do roughly an update of src/tools/msvc/ to
add a new option path to LLVM, and update install-windows.sgml to add
the new optional dependency. Note that including LLVM in the builds
means adding conditionally the files part of src/backend/jit/llvm/,
but one can take for example OpenSSL as a model of how it happens.
That would take care of the build. There may be some
Windows-dependent stuff needed to make JIT work properly on Windows
though.
