Note that because Crystal doesn't fully support Windows yet,
the Savi compiler still cannot run on native Windows.
But Savi programs can, after being cross-compiled.
After this change, it is possible to build 64-bit Windows binaries
from a Linux host running the Savi compiler, after setting the
SDK_ROOT environment variable to point to a directory tree where
the Windows SDK libraries can be found (such as an MSVC installation),
using a command like this:
Note that the Savi compiler includes the lld linker inside it,
so it is not necessary to have access to the full MSVC toolchain -
only the .lib files must be reachable within the SDK_ROOT tree.
One convenient way to automate the downloading of these libraries
on non-Windows platforms is xwin.
For example, running the following commands should be sufficient
(after reviewing the Windows SDK license and agreeing to its terms):
Note that not all of the Savi standard library works on Windows yet -
getting this new compiler with cross-compilation support for Windows
will allow the Savi team to iterate on bringing each library into
full Windows support and adding Windows CI to all repos.
