-  # We're almost certainly being configured before anything else which uses
-  # C++, so all of our AC_PROG_* discoveries will be cached.  It's vital that
-  # we not cache the value of CXX that we "discover" here, because it's set
-  # to something unique for us and libjava.  Other target libraries need to
-  # find CXX for themselves.  We yank the rug out from under the normal AC_*
-  # process by sneakily renaming the cache variable.  This also lets us debug
-  # the value of "our" CXX in postmortems.
-  #
-  # We must also force CXX to /not/ be a precious variable, otherwise the
-  # wrong (non-multilib-adjusted) value will be used in multilibs.  This
-  # little trick also affects CPPFLAGS, CXXFLAGS, and LDFLAGS.  And as a side
-  # effect, CXXFLAGS is no longer automagically subst'd, so we have to do
-  # that ourselves.  Un-preciousing AC_PROG_CC also affects CC and CFLAGS.
