# Autoconf will set CXXFLAGS; we don't usually want it to, because we
# either define our own flags (at least if GCC is in use) or else use
# the user's preferences.  We need to ensure CXXFLAGS is only set if
# the user has expressly set it.  So, save the user's (or empty)
# setting now and restore it after Autoconf has done its bit of
# piddling about.

# If the user supplied CFLAGS but not CXXFLAGS, use CFLAGS instead
if test x"$USER_CXXFLAGS" = x; then
