Fortran 90 had derived types, and Fortran 2003 had BIND(C) derived types - essentially C structs. I don’t see the logic of inventing an archaic “create type” routine when the user could just declared the required type directly. Cheers, Bill

Given that Fortran 90+ has user-defined types, I don't see any reason why we can't allow these to be used to make MPI_M**LOC reductions more useful in Fortran. See the following ticket for details. Please add comments to the GitHub issue.
