I guess the gdb environment is "cleaner" than raw windoze. Anyway. I noticed that some of the standard utilities were also behaving in weird manners, so I re-built the distributed from scratch (including running configure), and now everything works just fine. Chalk it up to perturbations created by debugging the original problem with setvbuf()! Tom Shields Christopher G.
