1. header file and source file protections using #ifdef WIN32
2. new files and directories to support windows functionality
3. appropritate linkage symbols added (OMPI_DECLSPEC) for windows
4. some functions are unimplemented on the windows side. this is mostly
because there might not be need to implement it in windows land. eg., forking
a daemon off
5. Introduced locking mechanisms for windows

- because we had the scenario, that fragments for a communicator, which was not
not yet set up on all procs, arrived and caused problem, we introduced
a comm_activate function call, which executes a kind of barrier (using
the allreduce functions used for the comm_cid allocation).
Setting up the coll-component has moved *after* this barrier, since
some coll-modules (e.g. the MagPIe component) might want to communicate
using this communicator already (e.g. a comm_split).
- adding a new file comm_dyn.c, which basically abstracts the required functionality
for connect-accept, and therefore is the 'magic' code (from the MPI point of view)
for all dynamically created communicators.

code base.
- many (most) mca type names have "component" or "module" in them,
as relevant, just to further distinguish the difference between
component data/actions and module data/actions. All developers
are encouraged to perpetuate this convention when you create
types that are specific to a framework, component, or module
- did very little to entire framework (just the basics to make it
compile) because it's just about to be almost entirely replaced
- ditto for io / romio
- did not work on elan or ib components; have to commit and then
convert those on a different machine with the right libraries and
headers
- renamed a bunch of *_module.c files to *_component.c and *module*c
to *component*c (a few still remain, e.g., ptl/ib, ptl/elan, etc.)
- modified autogen/configure/build process to match new filenames
(e.g., output static-components.h instead of static-modules.h)
- removed DOS-style cr/lf stuff in ns/ns.h
- added newline to end of file src/util/numtostr.h
- removed some redundant error checking in the top-level topo
functions
- added a few {} here and there where people "forgot" to put them in
for 1 line blocks ;-)
- removed a bunch of MPI_* types from mca header files (replaced with
corresponding ompi_* types)
- all the ptl components had version numbers in their structs; removed
- converted a few more elements in the MCA base to use the OBJ
interface -- removed some old manual reference counting kruft

real commit of the collectives. MPI_SCAN and MPI_EXSCAN are still not
implemented, but lots of other things are in the critical path and
holding up other people, so it's ok to commit without them:
- better checks for sizes in configure, and add defaults for fortran
sizes if we don't have a fortran compiler
- fix some logic that was accidentally broken for size checks for the
file type offset_t
- add some C equivalent types for fortran's complex and double complex
(for use in internal reduction/op functions)
- additionals and slight reorganization of ompi_mpi_init()
ompi_mpi_finalize()
- fully implement all top-level MPI collective calls, including all
param checking for both intra- and inter-communicators (woof)
- change the communicator_t type for stuff that we need in coll, and
update all references throughout the code base to match
- all kinds of updates to the coll framework base
- next cut of the basic coll module -- has all intracommunicator
collectives implemented except scan and exscan (see note above).
All intercommunicator functions return ERR_NOT_IMPLEMENTED.
- MPI_Op is a fixed implementation -- not component-ized yet. So
there are generic C loops for all implementations.

- for threaded case - cleanup event libraries progress thread
- cleanup of request handling for persistent sends
- added support for buffered sends
This commit was SVN r1461.
The reason is, that we had to pass four arguments to comm_sdet, which were just passed to comm_cid. However, for the dynamic case, even these four arguments are not enough. So I extracted it. A typical sequence for a comm-creation will therefore be:
newcomm = ompi_comm_set (...);
ompi_comm_nextcid (newcomm, oldcomm,...);
This commit was SVN r1312.
- added a function for implementing an allgather on the local_comm for inter-communicators. Will just be used from MPI_Comm_split for inter-communicators
This commit was SVN r1283.
Still to do:
- make the CID allocation routine thread safe
- add the ACK in lam_comm_free
- fix a bug in lam_comm_split for inter-communicators ( in this
case we can not have allgather_intra and allgather_inter at the
same time at this communicators, that's however what
the current implemention assumes).
