Better example code would be to prepend `set -e; ' to the
`for' loop.

(If one wants to disregard errors copying the files, then one should use
an explicit `|| true'; otherwise, an error copying the last file will
not be ignored.)

The Gnu standards for makefiles would additionally recommend that the
$(INSTALL) commands be written e.g.

	$(INSTALL_DATA) $$hdr $(INSTALL_INT_DIR)/$$hdr

where the default value of $(INSTALL_DATA) is `${INSTALL} -m 644'.
