Please > cancel if you disagree. Full debdiff attached. my last NMU got cancelled because you uploaded a new version of gcc-defaults while my NMU was still waiting in the delayed queue. On September 1, you told me in #debian-devel that this bug is on your TODO list but now more than two months have passed without anything having happened. So I uploaded another NMU of gcc-defaults with the maximum delay of 15 days. Please cancel if you disagree. Full debdiff attached. Thanks! cheers, josch
