always have display_timing activated for smpi, as it is quite useful
Merge branch 'master' of git+ssh://scm.gforge.inria.fr//gitroot/simgrid/simgrid
various fixes to hopefully compile under win32
remove a few unused things for win, but we have more bugs after ..
resolve cmakelists conflict
several changes in the way cmake handles windows
rename main function for windows
small fixes to repair unix build
bug : smpi tracing options were replacing those the user had set
small change for smpi win
add option to set the threshold where smpi send stops behaving like isend.
This was hardcoded to 65536, but experiments show that sometimes 327680 might be better
Revert "always have display_timing activated for smpi, as it is quite useful"

This reverts commit f641b68a3c807956396f8f70965ce9c4644dcfa5.
add support for Ssend/Issend in SMPI
activate a bunch of tests using mpi_ssend, and change back those where they had been changed to mpi_send
add an smpi/ois factor, to account for the fact that MPI_Send and MPI_Isend internal times may be differents
