KWSys.Process does treat stdout/stderr separately and has
many options to control them.  It can even be told to connect
the child process stderr directly to that of the parent
process.  RunSingleCommand does this with OUTPUT_PASSTHROUGH
for both pipes.  It could be taught another option to do
this only for stderr.  Or, cmcldeps could use KWSys Process
directly the way it needs instead of using RunSingleCommand.

As Nils pointed out, "deps=msvc" is already preferred.
