* include/shlib-compat.h (SHLIB_COMPAT): Take a third argument, indicating the first version set to obsolete the conditionalized code. * scripts/abi-versions.awk: For subsumed versions, make ABI_* defn's rhs be the ABI_* macro for the subsuming version. Assign increasing integer values to the ABI_* macros for supported versions.
