Greetings,

My company is contemplating using GNU libraries for our
next project.

Suppose we built an executable which links only to the open
source cygwin.dll and delivered only the executable _without_
also delivering cygwin.dll.  Would we be in breach of the GPL
if we refused to provide our independently-developed source
code needed to build the executable?

I believe we would not be in breach of the GPL because the
delivered executable, though depending on cygwin.dll, does
not contain any object code compiled from cygwin GPL'd source
code, but merely references symbols defined in cygwin.dll.

I've read the GPL and LGPL but don't feel certain my interpretation
is correct.  Can anyone help clarify on this issue?

Thanks in advance.

Lyman Neuschaefer
