1. When trying to add clang to a *-w64-mingw32 project, I get linker warnings:

2. llvm-strip fails: `llvm-strip: error: '/mnt/data/build/debug/dxvk-master/x64/dxgi.dll': invalid SymbolTableIndex`
https://github.com/doitsujin/dxvk/pull/5367
I use:
```
[marin@pc-linux x64]$ clang++ --version
clang version 22.0.0git (https://github.com/llvm/llvm-project.git 8462cff40daf40e58d705f5d86d4e91ef6e6294c)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /home/marin/install/bin
```
https://wiki.archlinux.org/title/MinGW_package_guidelines
https://archlinux.org/packages/extra/x86_64/mingw-w64-gcc/
3. Why the sections have different sizes ? I am guessing 16 is the good one for the platform? Can I specify the size on the command line?
```
[marin@pc-linux x64]$ size --format=sysv /usr/i686-w64-mingw32/lib/libstdc++.a | grep '.rdata$_ZTSSt9exception'
.rdata$_ZTSSt9exception 16 0
...
[marin@pc-linux x64]$ size --format=sysv /mnt/data/build/debug/dxvk-master/build.64/src/*/*/*.cpp.obj | grep '.rdata$_ZTSSt9exception'
.rdata$_ZTSSt9exception 13 0
...
```
