The change also means libgcc is now GPLv3 as well, making licensing for anything embedded that uses glibc (which has a hard dependency on libgcc_s) a royal PITA to figure out since GCC’s linking exception. Okay, so a proprietary program can link against libgcc without coming afoul of the GPL, but do we still have to make libgcc_s itself replaceable according the the anti-tivo clause?

The FSF is shooting themselves in the foot with the way they handle many of their projects today, GCC is no exception. Free software purity is a great goal and all, but what use is it when nobody uses it or it falls behind more permissively licenses projects.
