Although I occasionally cross-compile other projects from Linux to Windows, I haven't tried cross-compiling GCC itself from Linux at all.] It should be easy to build a native compiler without having a cross compiler first, as those pre-built CRT objects and libraries are already everywhere and can be copied into the build system directly, so configuring GCC with `--{host,target}=x86_64-w64-mingw32` for example should be enough for creating a native compiler. It is a cross binutils that is a must-have. -- Best regards, LH_Mouse
