EDG accepts the code.  With GCC 4.3 and newer we reject the code with

t.C: In function ‘int main()’:
t.C:32: error: cannot declare variable ‘s’ to be of abstract type ‘S3’
t.C:21: note:   because the following virtual functions are pure within ‘S3’:
t.C:16: note:   virtual void S2::f(int)

GCC 4.2 has this in addition to the CV error.  Of course the reason is the
same.

GCC never accepted the code, so this is not a regression.
