No problem, I hope you enjoyed it!

Ah, OK. In that case we have (or more exactly, we had) a bug in configure. I
can compile and run with the below change, which I couldn’t previously with
NEW_GC.

Examine $machine more carefully when choosing VDB implementation, NEW_GC

ChangeLog addition:

2011-09-05  Aidan Kehoe  <kehoea at parhasard.net>

	* configure.ac: $machine is intel386, reflecting the file name
	under src/m/, on i[3-9]86. Respect this when deciding on VDB_POSIX
	over VDB_MACH with the new GC.
	* configure:
	Regenerate.
