I have managed to build boost.mpi with openmpi on windows.
the mpi.jam available in the has some function that is unix shell specific.
When I tried to build with bjam, it failed because of this. This is the
function:


# Determine if it is safe to execute the given shell command by trying
# to execute it and determining whether the exit code is zero or
# not. Returns true for an exit code of zero, false otherwise.
local rule safe-shell-command ( cmdline )
{
  local result = [ SHELL "$(cmdline) > /dev/null 2>/dev/null; if [ "$?" -eq
"0" ]; then echo SSCOK; fi" ] ;
  return [ MATCH ".*(SSCOK).*" : $(result) ] ;
}

Under windows, I guess the /dev/null should be replaced by > nul, and the 
    if [ "$?" -eq "0" ]; then echo SSCOK; fi 
should be replaced by the cmd.exe equivalent :-)

I didn't actually do this as I just removed the if test that called this
function completely:-) and it built boost.mpi correctly.
However, I am available to test the windows fix if there is an interest,

regards,
