Romania (and perhaps Moldova) use EU rules for daylight saving

[Paul Eggert]

It seems that Romania used the EU rules as of fall 1998.  See:

I'm guessing that Moldova syncs with Romania, so unless we get better
info I'll propose a patch switching those two countries to EU rules in
1997, the same year as Bulgaria.
