It is supported. However on Windows GDC does not work. LDC based on LLVM needs Visual Studio but I maybe wrong since there are clang/llvm distributions based on mingw64. Other than that DMD works fine, a bit slower than the other compilers, but a charm to use.

Ldc like dmd ships lld and mingw import libraries and has for a few years now.

They both work out of the box without MSVC installed.

It's only ImportC feature that requires MSVC. The work required to get clang working in its place hasn't happened yet.
