There's a need for user information about when ABI incompatibilities
affect linking code built with different compilers or compiler versions.
But there's also a need for the technical documentation defining what the
ABI is, where this goes beyond the external standards (e.g., the ABI for
code using GCC extensions), and what the actual "3.2 ABI" is in cases
where it differs from the specification (whereas the user documentation
need only discuss what code is affected, not the detailed differences in
those cases). I feel that technical documentation fits better in the
internals manual.
