No dice :(

It's pretty weird, it bombs out if either src or obj is on NFS..
But even weirder is that if I build with crochet (a wrapper for cross building to arm) it works. It doesn't work if I cross build manually and I haven't been able to determine why crochet works yet.

Reaaaally frustraing :(

Nothing, they just get eaten. This isn't AmigaDOS! :)
