When upgrading a crossdev toolchain from gcc-4.8.2 to gcc-4.8.3, the following error occur : # emerge -uva1t =cross-x86_64-w64-mingw32/gcc-4.8.3 (..) Calculating dependencies... done!

Note that almost the same apply for =cross-i686-w64-mingw32/gcc-4.8.3
we probably need to restrict the auto-ssp logic to known targets only, like linux and freebsd
Same here with i686-w64-mingw32, x86_64-w64-mingw32 or i686-pc-mingw32 - note that https://bugs.gentoo.org/show_bug.cgi?id=513706 is related. The problem appears to be that most of gcc is built with -fno-stack-protector flag (unconditionally, not considering settings in /usr/i686-w64-mingw32/etc/portage/make.conf) and then some library functions are built without the -fno-stack-protector flag which now leads to the reported problem because -fstack-protector is default.
