linking against a GNU GPL (not LGPL!) library makes your program GPL, even if the library is dynamic (DLL). <http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/clisp/clisp/doc/Why-CLISP-is-under-GPL?rev=HEAD> therefore, if you distribute a program which relies on cygwin.dll (which, IIUC, is released under the GNU GPL), you have to either release the source code under GNU GPL, or buy a different license from the (C) holder (RedHat).
