Niclas refers to src/share/examples/etc/make.conf, which suggests
that he has CXXFLAGS defined in /etc/make.conf.

>From src/share/examples/etc/make.con, we find

  # 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.
  #
  #CXXFLAGS+= -fmemoize-lookups -fsave-memoized

kargl[193] c++ -fmemoize-lookups -fsave-memoized a.c
cc1plus: error: unrecognized command line option "-fmemoize-lookups"
cc1plus: error: unrecognized command line option "-fsave-memoized"
