As a reasonably recent example, adding bignum support by default added "GMP" to `system-configuration-features' when rebuilding after pulling upstream changes, without the user changing the configure command line saved in `system-configuration-options'. That kind of change may not happen often, but for developers building commits near the switchover point (e.g. git bisect), it adds a silent incompatibility that may be hard to diagnose. > Or maybe we should ask Andrea to try to provide a more detailed > definition of what exactly constitutes the "ABI" in this case. Adding some design notes notes to the repo on this and other aspects of the design would indeed be useful. AndyM
