[mpich-discuss] query ABI version

[Jeff Hammond]

Why not keep the ABI defined in the devel version?  Shouldn't you be
able to keep the ABI well-defined and change it when it needs
changing?

In any case, I do not really care.  This is about querying the ABI of
well-defined releases of MPICH and its derivatives.

For example, I want to be able to download a release of MPICH, build a
library against it and then be able to redistribute that library to
users that might build their application with Cray MPI or Intel MPI.
As a responsible library developer, I want to detect any ABI problems
as early as possible rather than have potentially silent errors.
Right now, it seems rather difficult for me to do this.
