openmpi/opal/mca/timer/windows/timer_windows.h
Rainer Keller fd28b392bf - An intrusive commit yet again (sorry): with the separation we
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
