There are two other regressions with patches:

4430 Regression(2.037) erroneous matching on specialized template function
3627 -of with a filename with a double extension confuses linker

If all those are fixed, we'll be down to 7 D2-specific regressions, 5
D1-specific regressions, and 2 which are common to both. (There are a
couple of other bugs tagged as 'regression', but which have never
actually worked correctly).
