Summary of the current changes
Redo manifest filename logic in "wx/msw/wx.rc".
The prior manifest logic failed to work under Clang64.
I know virtually nothing about MSYS2 packages but I wonder why are those changes necessary?
I have tried not that long ago and wxWidgets with the unmodified wx.rc builds just fine not only with GCC (package mingw-w64-x86_64-toolchain) but also clang (package mingw-w64-clang-x86_64-toolchain)?
Is there another clang package? I admit I have no idea if that package i listed uses its own resource compiler (llvm-rc) or mingw one (windres).
