For both x86_64-w64-mingw32 and i686-w64-mingw32 crossdev tries to build stage 1 of gcc right after binutils, which leads to it failing due to missing headers. In file included from /var/tmp/portage/cross-x86_64-w64-mingw32/gcc-9.2.0/work/gcc-9.2.0/libgcc/../gcc/tsystem.h:44, from /var/tmp/portage/cross-x86_64-w64-mingw32/gcc-9.2.0/work/gcc-9.2.0/libgcc/libgcc2.c:27: /var/tmp/portage/cross-x86_64-w64-mingw32/gcc-9.2.0/work/build/gcc/include/stddef.h:1:15: fatal error: stddef.h: No such file or directory 1 | #include_next <stddef.h> | ^~~~~~~~~~ compilation terminated. Manually installing the relevant cross-(x86_64/i686)-w64-mingw32/mingw64-runtime with USE=headers-only allows gcc stage 1 to build.
