No permanent harm done.  I *really* appreciate all the work that you're
doing on win32-nat.c.  You're adding features that I've been dreaming about
for years.

Which reminds me.  I have a patch pending that I really should apply.
It allows use of ">" "<" constructs from the command line.

Where did I put that patch?  Rustle, rustle...
