I only have access to a different compiler version.  What does yours do
after this series of commands (in a junk directory):

mkdir a b c d
cat >a/a.cc <<EOF
#include "b.h"
#include "c/a.h"
#include <stdio.h>
int x=0;
EOF
echo >b/b.h
echo >c/a.h
CC -Ib -I. -xM -c a/a.cc
echo $?

and what does it do with

CC -Ib -I. -xM -c a/a.cc -o d/a.o
echo $?

?  Over here, the second one triggers the error
| CC: Suffix mismatch between -o and produced file (should produce .i)

which prevents the dashXmstdout depmode to work.  I believe it's a
compiler bug, but don't know for sure (have only looked very briefly at
the documentation).

However, on this system
  depmode=makedepend source=a/a.cc object=d/a.o libtool=no \
  sh -x path/to/depcomp CC -Ib -I. -c a/a.cc -o d/a.o

works.  So, the question is whether `depcomp' needs to cut out any of
your $CPPFLAGS or $CXXFLAGS which could make makedepend barf.
