this is the big windows commit. there are more things which have gone into this than i can remember. but basically, we are looking for 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 This commit was SVN r3286. 2004-10-22 20:06:05 +04:00			`OMPI_DECLSPEC int mca_pml_base_open(void);`
starting integration of i/o forwarding framework This commit was SVN r3986. 2005-01-13 18:30:49 +03:00			`OMPI_DECLSPEC int mca_pml_base_progress(void);`
Change the orientation of the thread level determination in ompi_mpi_init(): we no longer query the components to see what they can support -- instead, we tell the components what they need to support (if they can't support it, they should disqualify themselves from selection). This involved a bunch of things: - pass the configure-time-decided OMPI_ENABLE_PROGRESS_THREADS and OMPI_ENABLE_MPI_THREADS constants to each framework selection function - eliminate mca_base_init_select_components() - eliminate all "allow_multi_user_threads" and "have_hidden_threads" kinds of arguments and aggregation from various framework selection and component/module functions - correctly determine the max MPI thread level that we can support and limit the final MPI thread level as appropriate during ompi_mpi_init() As a side effect, while editing nearly every MPI component I also did the following: - found 2 places (gm and ib ptls) where ompi_set_using_threads() was erroneously being called (I think this is left over kruft from misunderstandings by the original authors). I removed these. This commit was SVN r5055. 2005-03-27 17:05:23 +04:00			`OMPI_DECLSPEC int mca_pml_base_select(bool enable_progress_threads,`

committing the header file fixes for protection against C++ name mangling. This is a hge commit. Please make sure that your files are protected right. There is some redundan protection in that the protection has been added right at teh beginning and at teh end ion some cases even thught typedefs are not requred to be protected.
