<typeinfo> has an issue with clang when -static-libstdc++

[denchat]

issue: operator== symbol get duplicated on linking phase when compile with -static-libstdc++ on clang target x86_64-w64-windows-gnu

workaround: by conditioning __clang__ with always inline attribute as seen in

Issues when building with clang (duplicate libstdc++.a symbols) https://github.com/msys2/MINGW-packages/issues/1677#issuecomment-242980310

Do you mean errors like this: C:\mingw64\lib\libstdc++.a(bad_alloc.o): duplicate section `.rdata$_ZTSSt9exception[_ZTSSt9exception]' has different size
I get this when trying to build third-party software. Anything I can do?

I have the same problem. Hundreds of "sections of different size" and occasionally multiple definitions of operator == for type_info.
