unsupported option '-mwindows' for target 'aarch64-w64-mingw32' #64464
Description
When doing a native build of NSPR 4.35 on Windows on Arm using LLVM 17.0.0 RC1 I got the error unsupported option '-mwindows' for target 'aarch64-w64-mingw32'.
However when building for MinGW-w64 the -mwindows is normally supported (at least I know it is for GCC).
Full output:
