We finally landed the long-promised fix for Unicode on Windows in upstream binaryen. It should appear in either release 116 or 117.

The fix we made last month for missing DWARF passes caused an unanticipated link-time regression for projects that also link to LLVM, since the DWARF passes reuse LLVM code, causing conflicting symbols. We have not decided on a fix yet.

Binaryen has released version 115 and 116. We will skip 115, and are working through some problems attempting the 116 upgrade.

There are two months remaining in this contract. I intend to fix the linkage regression, and get wasm-opt updated to the latest revisions of binaryen. I do not expect to have a solution for the cc rebuild times, as I don't have a plan yet that I am confident in, and the demand for it has been relatively subdued.
