For a target 'foo', Automake uses a foo_LINK variable, for which it provides a default definition. Since you are not satisfied with this default definition, you can and should provide your own definition of this variable. You can then decide yourself whether it uses --tag=CC or --tag=CXX and $(CCLD) $(AM_CFLAGS) $(CFLAGS) or $(CXXLD) $(AM_CXXFLAGS) $(CXXFLAGS). See e.g. in gettext/gettext-tools/src/Makefile.am the 'msgmerge' target and the msgmerge_LINK variable. This definition has been in use for ca. 20 years. Bruno
