Hi,
That's fine. I appreciate all the help.
Thanks for the explanation about configure. Makes sense!

Ok, I didn't understand your issue before. I thought your issue was with MPICH not agreeing with OpenMPI. That needed to be fixed anyways, so it's good that your query prompted it, but I'm sorry it wasn't what you needed.
MPE already has MPE_CONST, but it will be "const" whenever MPI_VERSION>=3, which is what late-model MPICH will give you. The solution is probably to the logic below to allow for manual override, rather than OR-ing on MPI_VERSION, which cannot be overridden.
#if defined(HAVE_CONST_IN_MPI_DECL) || MPI_VERSION >= 3
#define MPE_CONST const
#else
#define MPE_CONST
#endif
I'll try to work up a patch later.
As for configure, the documentation is rightly written for the user who downloads a release tarball, not the git repo. So yes, you should generate it with autogen.sh.

MPICH decided to follow the same convention as MPI_Type_create_struct with the const additions. Open MPI decided to keep the old prototypes as is.

We'll figure out what to do about that internally, but that's not going to be a quick change because of ABI and other such stuff.
