It is the intention to support MSVC: https://github.com/mozilla/rust/issues/1768
However, Rust really needs Windows-savvy developers! If you can help, please do.
Seems like there are a few straightforward "fixables" in there.
"Does it run on Windows?
Yes. All development happens in lock-step on all 3 target platforms. Using MinGW, not Cygwin. Note that the windows implementation currently has some limitations: in particular tasks cannot unwind on windows, and all Rust executables require a MinGW installation at runtime."
