Sorry for a delay, just noticed this request.

TinyGC was designed as a straight-forward minimalist portable implementation of BDWGC API sufficient for Java VM implementation. It is not designed for speed.
GC_free is not implemented because GC-allocated memory is freed automatically.

As for using GC on sabotage linux, it is better to invest time in porting BDWGC to this target.
