 You don't *have* to use the same CXXFLAGS options as the ones of the
 example.  It's an example, after all.  Anyway, would you prefer something
 like this instead?
 
     # CXXFLAGS controls the compiler settings used when compiling C++ code.
     # Note that CXXFLAGS is initially set to the value of CFLAGS.  If you wish
     # to add to CXXFLAGS value, "+=" must be used rather than "=".  Using "="
     # alone will remove the often needed contents of CFLAGS from CXXFLAGS.
    +# For a description of the options recognized by the GNU C++ compiler
    +# please refer to the c++(1) manpage and the info documentation of GCC.
     #
    -#CXXFLAGS+= -fmemoize-lookups -fsave-memoized
    +#CXXFLAGS+= -O -pipe
