Well, I think -MM only works with gcc like compilers, so we did this:
In configure.ac, we added:

Part of the change above is because on AIX with xlC GXX was not set to
no, but was empty, so the configure script required user interaction
when xlC spewed its help page to make the help page go away.

And in Makefile.in we changed:
-makefile.dep:
-       $(CXX) -MM $(CXXFLAGS) $(CPPFLAGS) $(SRCS) > $@
-include makefile.dep
+@HAVE_GXX@makefile.dep:
+@HAVE_GXX@     $(CXX) -MM $(CXXFLAGS) $(CPPFLAGS) $(SRCS) > $@
+@HAVE_GXX@include makefile.dep

We have some more patches coming, but not complete yet.
