--- Comment #4 from Mojca Miklavec <mojca at macports dot org> --- I'm sorry, I forgot about this ticket. I can confirm that building (version 11.1) in fact works on all macOS versions at the moment https://ports.macports.org/port/x86_64-w64-mingw32-gcc/details/ It's only broken for i686 on 10.6, but that's a completely different issue that we need to investigate separately at some point. (ld: illegal text-relocation to ___stdoutp in /usr/lib/libSystem.dylib from _main in build/gengenrtl.o for architecture i386)
