Ok, sorry, but I don't understand that.  What has the GPL to do with that
in terms of the application under the BSDPL license, which explicitely
refuses to put anything of it under the GPL?!?  You can't comply to both
licenses for that reason.

Also, AFAICS, that's not about distribution, but it's about linking
against the Cygwin DLL.  If you do that with an application which has
a non-approved OSS license, you're infringing the Cygwin license if
you don't GPL the code.  But if you GPL the code, you're infringing the
BSDPL license.  So I don't see a satisfactory way out.

Honestly confused,

P.S.: I won't object against including this application but I'm not
convinced that it's right to do that.  

P.S.#2: IANAL, which is pretty obvious from the above discussion.

P.S.#3: And I never wanted to be a lawyer.
