Created attachment 874572 [details] build.log app-emulation/wine-proton-8.0.4 fails to build withcross-x86_64-w64-mingw32/gcc-13.2.1_p20231014::crossdev and cross-i686-w64-mingw32/gcc-13.2.1_p20231014::crossdev due to error: conflicting types for ‘powf’; have ‘float(float, float)’.

Seem like this issue has been caused by setting CPP="clang-cpp" in make.conf, but not correctly overriding it in the compiler-gcc env profiles. This can be closed I think.
If you don't use mingw for anything else than wine, I'd personally recommend to just USE=-crossdev-mingw and use mingw64-toolchain instead (note that wine-proton *always* use mingw, so disabling that won't give you a PE-less build) It also builds fine with clang last I know of (last tested with clang 17.0.x or so and with musl), and should save you a hassle in general.
