Thank you for testing it.  I neglected to mention that I did a fair bit
of investigation before hand and was able to confirm that all platforms
we care about (Windows, Linux/Unix, OS X) and all compilers we care
about (GCC, LLVM) support weak symbols.

There may be different attribute names across compilers--it wasn't very
clear to me, but they definitely all have the feature in some form.
