both samples in separate directories

I don't know what of the following is a bug because of there is a lot of strange behaviour so I prefer describe it step-by-step.

PREAMBLE.
Situation in brief. I have a group containing set of structures. Each structure has set of functions and function-like macroses.

And I want to display both functions and function-like macroses both upon group and structure page.


OBSERVATION-1.
So I add \relates <struct> and \ingroup <group> in documentation block. Such way formatted block produces the proper result (for me) while documenting function but not the macro (tss_del_base vs tss_del_base_back in sample1). This seems to be a bug.


OBSERVATION-2.
If I remove @relates (leaving @ingroup) then then macro naturally disappears from structure documentation page but on group page it is displayed almost as wanted(i.e. the only item). See behaviour of tss_del_bof_back_norel in sample1. So this looks like absolutely normal behaviour.
If I remove @ingroup (leaving @relates) then macro is displayed both on group and structure documentation pages BUT it is doubled on group documentation page. See behaviour of tss_del_bof_back_nogrp in sample1. BUT if delete tss_del_bof with its documentation then duplication becomes automatically removed (this is illustrated by sample2). So this seems to be definitely a bug.

OBSERVATION-3
To avoid such strange behavious I've even tried to document macro as function (see documentation for tss_del_bif_copy) and this produces almost ideal result, but there is a little drawbacks:
 1. doxygen generates 2 warnings in my case:
1/sample.h:109: warning: argument 'id___' of command @param is not found in the argument list of tssBifFile::tss_del_bif_copy(rtsp_uint64 id___)
1/sample.h:109: warning: The following parameters of tssBifFile::tss_del_bif_copy(rtsp_uint64 id___) are not documented:
  parameter 'rtsp_uint64'
 2. In documentation block for such function argument type is merged with argument name.
