Also, if you do have lots of users downloading prebuilt binaries then you must be already building them for a variety of different OS/hardware/compiler combinations, in which case the simplest solution would be to simply add another build option. That way you offer two separate builds, one with the new ABI and with the old. I strongly recommend you do that.
