>Description:
Set lists that mark obsolete files (for instance
src/distrib/sets/lists/comp/md.amd64) haven't been updated since GCC
was updated to 4.8.3 to mark files in /usr/include/gcc-4.5 obsolete.

>How-To-Repeat:
Upgrade an arch that now has GCC 4.8.3 and notice that postinstall(8)
doesn't clear out /usr/include/gcc-4.5.
>Fix:
Update the sets. (Obviously this isn't a burning issue, though...)
