FWIW, I don't know what there is to rework - the current libc++ should work just fine on Windows 7 with mingw-w64. The msvcrt releases from e.g. https://github.com/mstorsjo/llvm-mingw/releases/tag/20250613 work just fine on Windows 7 (I just tested it), and yesterday I checked a libc++.dll from a nightly build of latest llvm git which also loaded fine.
