Looks good. In particular, I think we always need to pass

with this technique.

I avoid 'make --include-dir' because I couldn't find a way to prevent
"macro" makefiles (that are included in many makefiles) from being
remade repeatedly, unless I included them by absolute pathname:
  include $(SRCDIR)/configuration.make

As for

(which you write outside the $(MAKE) command of course), don't you
really want '-I${CURDIR}' at the beginning of your include list?
If someone does 'make CPPFLAGS="-I/foo/bar/"' and /foo/bar/ just
happens to have a header whose name shadows one of yours, then
yours in SRCDIR won't be used.
