Generating two versions of the constructor is what g++ usually does, as 
can be seen on any trivial example:
struct A{A();}; A::A(){}

(although now on several platforms the 2 names will actually point to the 
same address)
I find it more surprising that one of them is missing on sparc. And since 
you get this with both Sun and GNU linkers, it doesn't seem like it can 
have removed the unused one.
