MNo, I didn't NAK it. Quite the reverser.

I am ABSOLUTELY against rebuilding normal object files just because
gcc versions change. A compiler version change makes zero difference
for any normal object file.

But the gcc plugins are different. They very much _are_ tied to a
particular gcc version.

Now, they are tied to a particular gcc version because they are
horribly badly done, and bad technology, and I went off on a bit of a
rant about just how bad they are, but the point is that gcc plugins
depend on the exact gcc version in ways that normal object files do
_not_.
