Based on what you wrote above, it sounds like it should be fairly
straightforward to write a configure test to detect whether the old and
new versions are compatible. (I guess this equates to whether
curl_off_t used to be 32 bits and is about to become 64 bits, if I've
understood the issue correctly.)

That being the case, it should be possible to refine your option (4):
reserve a new -version-info and have the configure script select it only
for the specific platforms that are going to break.
