Version 3 and 4 were very different
Version 4 and 5 are very different
Subversion changes (between 4.3.2 and 4.3.3 or 5.2 and 5.3)
have a chance of compatibility if your code wasn't doing
something that dependant on something in the later libraries,
especially if you were usng the same compiler version on both
systems.
