3PP source code question (IANAL)

["DePriest, Jason R." <jrdepriest at gmail dot com>]

Are 3PPs that bundle an old version of cygwin1.dll required in any way
to provide the source code of their app so that I can recompile it
with a modern version of cygwin1.dll?

I have used Foundstone's (now part of McAfee) free tools (found here
http://www.foundstone.com/resources/freetools.htm) for some time and a
few of them use the cygwin dll (Pasco, Galleta, Rifiuti).

However, only Pasco
(http://www.foundstone.com/resources/proddesc/pasco.htm) includes the
source code.

They are all bundled with this cygwin1.dll:

The dll is over three years old!

Should I even bother trying to get the source code out of them?

Thanks.
