--------------------------------+-------------------------------------------
 The current approach of supporting debugging iterators in the {{{+debug}}}
 variant of boost (see #20478) has a drawback: You get a linker error if
 you try to link some program that was compiled without
 {{{-D_GLIBCXX_DEBUG}}} (i. e. without debugging iterators) with the boost
 program options library compiled with the {{{+debug}}} variant. This is
 the case for both the normal library {{{libboost_program_options-
 mt.dylib}}} and the debugging library {{{libboost_program_options-
 mt-d.dylib}}}.

 I propose to add a new variant for debugging iterators and remove
 {{{define=_GLIBCXX_DEBUG}}} from the {{{+debug}}} variant.
