-# 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.

# -fno-builtin must be present here so that a non-conflicting form of
# std::exit can be guessed by AC_PROG_CXX, and used in later tests.
