 	Ah, yes.  I am dumb.  I can compile and run it without problems 
with just the two *eay32 dlls.

 	And we've finally figured out the other bug, where it works on my 
computer, and not on someone else's.  It has to do with ipv6 support, and 
it didn't go away even after I ./config  --disable-ipv6, which that flag 
is (mostly?) ignored in the windows builds, due to the dynamic LoadLibrary 
calls.  On one computer, stunnel connects on the ipv6 port, but then when 
running "telnet localhost 7000", it connects via the ipv4 port, and so 
fails.  If we force stunnel to use ipv4 by using 127.0.0.1 instead of 
localhost, everything works fine.  My guess is that his computer is 
partially/incorrectly configured for ipv6, and so that is the reason for 
the failure.  I'm planning on removing the LoadLibrary calls to force ipv6 
to be off, though it'd be nice to not do that, since someday, there will 
be an ipv6-only network that we'll have to deal with presumably.
