If pkgsrc is trying to build gcc3 something is very wrong, this basically

At this point in time we should probably just make this more explicit.
Rip out gcc48 and earlier, and convert the GCC_REQD 2.x/3.x stuff into
a "could not find host compiler" error.
(I have no problem with the 'needing gcc3 is a sign of very bad things' notion.)
I think it would be good to avoid breaking pkgsrc on systems that are
really old but not quite ancient. I draw the line at netbsd-5 which has
gcc 4.1. Yes, that's really crufty, but a lot of things build, and
while pkgsrc does not "support" such a system, I'd like to avoid moving
it to "completely fails".

"Versions of GCC prior to 11 also allow bootstrapping with an ISO C++98
compiler, versions of GCC prior to 4.8 also allow bootstrapping with a
ISO C89 compiler, and versions of GCC prior to 3.4 also allow bootstrapping
with a traditional (K&R) C compiler."
It's why I proposed deleting all the priors and reimporting 4.7, but
not even 4.7 should be necessary with netbsd-5, since the compiler has
C++98 support.
