In what version of OS X was libstdc++.6.dylib updated to point to libstdc++.6.0.9.dylib

Question

One obvious workaround to my earlier question about getting an application to run on OS X 10.5, is simply to drop support for that version.

But that leaves the question of what version of OS X I'd need to set as my minimum deployment target, in order to solve the link errors pasted below (described in more detail in the earlier question)?

Dyld Error Message:

In what version of OS X was libstdc++.6.dylib updated to point to libstdc++.6.0.9.dylib?

Answer 1

We tried upgrading to OS X 10.6.3 and libstdc++.6.dylib definitely points to libstdc++.6.0.9.dylib in that version.

(Presumably the change was made in 10.6.)
