I'd also seen one list member draw that conclusion, but for the life of 
me I can't see why.  I'm connecting from a Linux host, and the error 
appears to be printed by Cygwin's bash.exe.

bash.exe doesn't appear to be linked to that dll on either host.  I do 
notice that /cygdrive/c/WINDOWS/system32 appears before  
/cygdrive/c/WINDOWS/sysWOW64 in the PATH.  I know nothing about Windows' 
linker or loader, so I don't know if that could be a problem.  Is there 
any way to change it system-wide for Cygwin?  On the broken 64 bit host:
