I think you need to copy them to $(INSTALL_INC_DIR),
i.e. .../lib/mercury/incs, as well as to $(INSTALL_INT_DIR),
i.e. .../lib/mercury/ints.

Rather than doing it by hand, you can do this by adding a new target
in your Mmakefile,

	MYLIB_C_HDRS = c_object1.h c_object2.h

	.PHONY: libmylib.install_c_hdrs
	libmylib.install_c_hdrs:
		for hdr in $(MYLIB_C_HDRS); do \
			$(INSTALL) $$hdr $(INSTALL_INT_DIR); \
			$(INSTALL) $$hdr $(INSTALL_INC_DIR); \
		done

and adding a dependency to ensure that this target gets invoked:

	libmylib.install: libmylib.install_c_hdrs
