I suppose this can be mitigated by using #include "path/to/file.h" in
source, for paths relative to a small number of search-roots
(e.g. top-level SCM check-out roots; all #include paths are relative to
these) so that you only pass -I for these few roots, rather than the
idiom I've seen in some places of always using #include <file.h> and
passing a -I for every directory in the universe.
