Why is it a GCC issue to support a GC for ML, I don't get it ...

ML programs are mostly functional and allocate lots of small objects with very short lifespans. Without GC support in GCC, you're basically stuck with some sort of conservative collector. And that is unlikely to result in acceptable throughput.

Not clear what "in GCC" means here, seems to me you could perfectly well handle this with a combination of front end stuff and run time routines.
