As far as I understand them, these are mere API compatibility
rules, i.e. not to change existing API functions and structures.
As long as the same compiler and target system is being used,
the result will be an unchanged ABI.

For C code, no further formal ABI definitions should be necessary.
The few possible issues are addressed implicitly (APR memory
pools) or decided on demand (exceptions / signaling).

For C++ bindings, that will not be enough. Too many things are
(compiler) implementation dependent.
