Not a open source problem... 
Most open source project have a public stable interface (like Gnome) that is 
used for all major version.
Personally I don't like extreme backward portability... you carry on even bad 
design (do you think that x86 platform is good for nowadays computer??)...
In FreeTDS we mantain the public library (ODBC, dblib and ctlib) but libtds 
is suitable to change without problem.
Similar role apply also to Linux Kernel... but for avoid performance penalty..
