Error: There is no specific subroutine for the generic ‘sort_index’

I’m curious why this parameter is named int_size instead of int_kind.

@RonShepard

It is a little confusing since the term “size” is used in the documentation to describe the size of array(:) and index(:).

I don’t remember why it has been called int_size. But it could be renamed, if users find/prefer a more appropriate name.
