- creating the stack work now even for contiguous data (with gaps around) and independing on the fragment size. - add a TYPE argument to the PUSH_STACK macro. It's too obscure to explain it here :) - in dt_add we avoid surrounding a datatype with loops if we can handle it by increasing the count of the datatype (only if the datatype contain one type element and if the extent match). But it's enough to speed up a lot the packing/unpacking of all composed predefined datatypes (line MPI_COMPLEX and co.). - in dt_module.c improve the handling of the flags for all composed predefined datatypes. There is still something to do for the Fortran datatypes but it will be on the next commit. This commit was SVN r5879.
