The plperl stuff is actually a tough case. In 7.4 we didn't have
provision for two interpreters, so PERL_SYS_INIT3 is called
unconditionally, and we didn't have a Windows port either, so the

I guess that in itself illustrates the problems.
I also entirely agree with your point about us being more kludgey and
less invasive on back branches.
