Looking at diffs (attached) between the Makefiles in the toplevel and libcpp
subdirectory before and after drow's changes, I don't see any significant
differences in the libcpp level Makefile. However I suspect the problem with
the CPPFLAGS becoming unset after drow's patch is due to the instance of...

Wouldn't setting CPPFLAGS= to a null string effectively undo the previous
exports of CPPFLAGS?
