The ChangeLog formatting is wrong. The above line should be:
* Makefile.am (libgompd_la_SOURCES): Add ompd-parallel.c.
i.e. tab, * space filename and if there is something in the
file that is being modified, followed by space ( name )
All this then followed by : and description.

We aren't very consistent on the map files, either it should be
* libgompd.map (ompd_get_curr_parallel_handle,
ompd_get_enclosing_parallel_handle, ompd_rel_parallel_handle,
ompd_parallel_handle_compare): Export at OMPD_5.1.
or
* libgompd.map (OMPD_5.1): Export ompd_get_curr_parallel_handle,
ompd_get_enclosing_parallel_handle, ompd_rel_parallel_handle and
ompd_parallel_handle_compare.

This is totally wrong.
You are modifying the GOMPD_FOREACH_ACCESS macro I think.
So you should say
* ompd-support.h (GOMPD_FOREACH_ACCESS): Add
gompd_access (gomp_team_state, team) and
gompd_access (gomp_team, prev_ts).

Formatting. You can see the two lines are badly indented, each one in
a different wrong way. The indenting rule is that the lines after the first
one in this case should start aligned below context on the GET_VALUE
line, and each 8 spaces should be replaced by a tab.

Likewise.

Why the ()s around enc_par_handle?
Anyway, seems like an aliasing violation, if the callback stores
through void **, then you should just pass it address of a local
void * variable and *enc_par_handle = (ompd_parallel_handle_t) var;

Likewise (both aliasing and the unnecessary ()s.

Why?
