The sock channel expects VC to be UNCONNECTED to successfully post a connect on the VC. Changing VC to *STATE_UNCONNECTED before posting a connect on a VC for the sock channel

Check if the errcodes are not null before broadcasting them. If the application specifies MPI_ERRCODES_IGNORE, it'll be NULL.

MT: Removed posting multiple connects for a VC. MPIDI_PG_GetConnString() can block and release the lock allowing another thread to try posting a connect for a VC in the VC_STATE_CONNECTING/VC_STATE_CONNECTED state.

(1) Added check for the latest version of VS runtime dlls (2) Updated the link for obtaining the .NET framework -- now all http links in installables are generic

1) Removed ib & sshm channels (2) Removed/Updated configurations referring ib & sshm channels (3) Corrected the Ctrl chars on makewindist.bat -- now compatible with windows (4) Now the default build is the Release build

causes hang when everyone else does an allreduce.

Make detection of a mismatch in the C and Fortran integers an error, since in that case we cannot build a correct Fortran interface

Handle the case of a Fortran compiler that has reals and double precision the same size (e.g., g59 with the -r8 switch)

changed top-level configure to make MPI_THREAD_FUNNELED the max thread level for channels which do not specify one

removed implicit null from spawnargvf.f and spawnmultf.f tests because the old sparc compilers don't have a declaration for iargc()

Added barriers in between different iterations to make sure that leaf nodes don't send data to the root faster than it can receive.

fixed improperly declared variables in test programs.  A variable called aint would be declared in an .h file, but the test program assumed the variable would be called asize, and v.v.  Implicit none was added to all programs/subroutines/functions to catch any such errors in the future.
