On a related note, I learned yesterday that I can bend Automake to my will by adding this to Makefile.am:
LIBTOOL = @LIBTOOL@ $(LIBTOOL_TAG) and then externally pass a tag option like make CXX='foo' LIBTOOL_TAG='--tag=CXX' I believe that Automake would be more robust with Libtool 1.5 and later if it automatically provided the --tag= option to libtool. Many leak-check tools (and perhaps other kinds of tools) are designed to replace the normal compiler. Usually they invoke the same compiler that was used by configure. Since this causes a compiler name change, the libtool does not work without a --tag=lang option.
