Fully static C++ linking?

[FelixBer]

Hi,

I understand these toolchains are designed to link dynamically against msvcrt / ucrt, but I am wondering what's missing for fully static C++ linking using Clang/LLVM on Windows and without any microsoft libs (libcmt, libcpmt, libvcruntime, etc.)

Since you take the startup code from mingw, shouldnt the LLVM libc be sufficient to fill in the "gap" between that and libc++? If not, what's missing?

Thanks,
