Thanx :)

Pretty much. The target tried was i386-hixs-elf (hixs is a layer that
replaces the syscalls with "hooked" versions - i.e. function
pointers). I haven't worked with x86 for years, so it might be me
forgetting something (protected mode stuff?).

I just swapped the target from an existing PowerPC set-up because I'm
currently in an area not strictly architecture dependant and I needed
something faster than the remote GDB box I'm currently using.

yes, I figured that too.

OK, thanx.
