It isn't clear what you call "state" above. The state of the world is
that GCC 4.1 is definitly in field and I still expect GCC 3.4 being
actively used on Solaris at least (I'm aware of SmartOS, but not every
Solaris is SmartOS).

Yes, we maintain pkgsrc on FreeBSD. At least I do, even though I do not
maintain it proactively. It is usually enough not to break it intentionally.

If a package builds, it doesn't mean that it works or implements
reasonable subset of functionality. E.g. sysutils/libvirt on NetBSD,
or editors/emacs* on NetBSD 6 (after removal of pseudoterminal nodes).
Thus I do not see why just building packages keeps QA level.
Even if you makes pkgsrc to run tests, many interesting packages either
do not have them or do not pass all of them.

The list of supported platforms is published quarterly.

GCC 3.4 was the main compiler on Solaris at most a year ago.
Note that it wasn't one of many GCC versions available, it was
_the_ compiler unless you had access to SunPro.

Except it is a hack and thus should not be applied blindly.

I don't see why it was a bad decision. If one follows that approach,
one could easily assert that the whole NetBSD is badly designed
since it uses -Werror for almost everything. I can't say much about
DragonFly, but FreeBSD followed the same trend of raising warnings
