dnl CXXFLAGS - C++ flags to use during the configure script run and
dnl during ACE compilation. The user may set this prior to
dnl running the configure script. As such, it is important
dnl not to replace the existing value of CXXFLAGS; rather
dnl one should only add to it.
dnl ACE_CXXFLAGS - General C++ flags the configure script should set before
dnl CXXFLAGS to allow the user override them.
dnl DCXXFLAGS - C++ debugging flags
dnl OCXXFLAGS - C++ optimization flags
