Yep. I'm sure. Phil did an excellent job.
You'll see this with the link map support on when building the .so:
-Wl,--version-script=linker.map -Wl,-soname -Wl,libstdc++.so.4 -o
.libs/libstdc++.so.4.0.0
Without it:
-Wl,-soname -Wl,libstdc++.so.4 -o .libs/libstdc++.so.4.0.0
Then, after you've created a shared executable, the undefined symbols are
versioned, like so
nm a.out | grep GLIBCPP_3.1
[snip]
U _ZNSt6locale5_ImplC1ERKS0_j@@GLIBCPP_3.1
U _ZNSt6locale5facetC2Ej@@GLIBCPP_3.1
U _ZNSt6locale5facetD2Ev@@GLIBCPP_3.1
U _ZNSt6locale7classicEv@@GLIBCPP_3.1
ok?
