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

IMPORTANT NOTE: when sendout ompi_output() strings to files, note that
the file goes into the session directory. If the session directory
does not exist yet when you call ompi_output() and you are sending the
string to a file, THE STRING WILL BE DROPPED (in terms of the file --
it will still be sent to all other locations that were specified).
This should really only be a factor for a fairly small portion of
things during initialization of a process -- basically, until the
session directory exists, nothing will be written to a file.
ompi_output() will automatically take care of creating the file and
writing to it once the session directory has been created. So it is
valid to:
id = ompi_output(...something with file set...)
ompi_output(id, "blah!");
/* ... process session directory is created ... */
ompi_output(id, "wazzlebort!");
In this case, the output file will be:
-----
[WARNING: 1 lines lost because the Open MPI process session directory did
not exist when ompi_output() was invoked]
wazzlebort!

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.
