Foundstone Labs has a few free tools they release that are compiled
against the cygwin1.dll.
The free tools are:
pasco (http://www.foundstone.com/us/resources/proddesc/pasco.htm)
galleta (http://www.foundstone.com/us/resources/proddesc/galleta.htm)
rifiuti (http://www.foundstone.com/us/resources/proddesc/rifiuti.htm)
Pasco includes its source code and is probably okay on that part, but
it doesn't include the text of the GPL and the cygwin1.dll file has a
BuildDate of '2003-03-18 09:20' and a File and Product Version number
of 1.3.22-dontuse-21
I can recompile it with the source and it works fine.
The other two products, galleta and rifiuti, ship with the same
version of cygwin1.dll but don't have the source code or the license
text.
