annotate test/suite_aggrs/rand-sig.lua @ 461:236015fdf7a8
suite_aggrs:
- added support to gen unions in addition to structs
- regenerated struct/union-mixed and nested cases
- made rand-sig.lua ignore closing struct/union chars if not opened, effectively reducing number of empty aggregates as it now generated way too much
