How do you think about the following approach to determine which source
files can be tried to compile even when interface descriptions are
(temporarily or intentionally) not available?


source_dir::=$(abs_top_srcdir)/$(TARGET)/
ml_sources::=$(addprefix $(source_dir),$(SRC))
mli_sources::=$(wildcard $(source_dir)*.mli)
modules_without_mli::=$(filter-out $(basename $(mli_sources)),$(basename 
$(ml_sources)))
$(info modules_without_mli)
$(info $(sort $(modules_without_mli)))

$(modules_without_mli): %.cmo: %.ml
        $$(OCAMLC_CMD) -c $$<


Unfortunately, corresponding messages seem to indicate that my knowledge
and understanding is still incomplete for the application of
static pattern rules.
