get bitten by header depending on having already included
the corresponding [opal|orte|ompi]_config.h header.
When separating, things like [OPAL|ORTE|OMPI]_DECLSPEC
are missed.
Script to add the corresponding header in front of all following
(taking care of possible #ifdef HAVE_...)
- Including some minor cleanups to
- ompi/group/group.h -- include _after_ #ifndef OMPI_GROUP_H
- ompi/mca/btl/btl.h -- nclude _after_ #ifndef MCA_BTL_H
- ompi/mca/crcp/bkmrk/crcp_bkmrk_btl.c -- still no need for
orte/util/output.h
- ompi/mca/pml/dr/pml_dr_recvreq.c -- no need for mpool.h
- ompi/mca/btl/btl.h -- reorder to fit
- ompi/mca/bml/bml.h -- reorder to fit
- ompi/runtime/ompi_mpi_finalize.c -- reorder to fit
- ompi/request/request.h -- additionally need ompi/constants.h
- Tested on linux/x86-64
