Yes, because I'm trying to use the exe's from tools.zip from within a 
cygwin bash window (because I find it a pain to use different command lines 
for different tasks, and I use cygwin bash for everything else.)  As far as 
I can remember, this used to work until a few months ago.  Now I find I 
have to remove the cygwin1.dll that came with tools.zip to get things to 
work.  It sounds like Duncan has a similar experience.

BTW, thanks for the tip on msinfo32.exe.  Curiously, for under Windows 
2000, it doesn't show a cygwin1.dll loaded, even though I have a number of 
cygwin bash windows running.  It shows 'cygintl-1.dll', 'cygintl-2.dll', 
'cygiconv2.dll', 'nice.exe', 'cat.exe', and 'sleep.exe' (as well as many 
other files not related to cygwin.)
