[Ns-developers] Deprecated Attribute?

I've been trying to track down when the -Wno-error= feature became available
in gcc. It is not in the gcc 4.1.2 manual. It is in the gcc 4.2.4 manual.
The addition of the feature doesn't appear in the gcc 4.2 release series
"changes, new features and fixes" documentation, though, but I do find it in
an old gcc 4.2.0 warning options page.
I didn't get a reaction when I wrote this in another email; but it does mean
that the first time someone actually checks in a change using the deprecated
attribute, we effectively set a requirement for gcc >= 4.2.0 on our builds.
This would break the build on ns-regression and darwin-ppc, my mac at home,
and my cygwins at work and at home -- at least until I managed to update all
of the compilers that I use, or go edit wscripts to try and turn off -Wall.
That doesn't sound to me like what we wanted to accomplish by adding this
attribute. Do we really want to do this?
