Andrew,

Actually, the #includes were dropped deliberately, and you've done the piece
what was SUPPOSED to happen and somehow got dropped: moving the decls to 
defs.h and defns to utils.c.  Thanks.  I must be careful not to overlook
mere warnings (speaking of which, it would be a nice goal to remove all
warnings from GDB compilations, lest they distract).

It does make one long for fast GC, does it not?  Or perhaps something 
region-based, where the region gets deallocated at, say, a point in the
top-level command loop.
