- new test/callback_suite_aggrs (currently ahead of checked-in dyncall code and won't compile, though, as with call_suite_aggrs; dc code will be checked in, soon)

+callback_suite_aggrs for dyncall written in C and Lua.
+
+Tests getting aggregates (structs, unions and arrays) back from a callback to
+whom they were passed by value, along with other, non-aggregate args. Note,
+arrays are only passed/returned by value as members of structs and unions, as
+they would decay to a pointer in C if passed to a function, and cannot be
+returned.
+So this test suite does not generate any arrays outside of structs and unions.
+
+A macro AGGR_MISALIGN can be used in globals.c to intentionally misalign
+aggregate instances used with callback object.
