*** NOTE ***
In accordance with section 10 of the GPL, Red
Hat permits programs whose sources are distributed under a license that
complies with the Open Source definition to be linked with libcygwin.a
without libcygwin.a itself causing the resulting program to be covered
by the GNU GPL.
This means that you can port an Open Source(tm)
application to cygwin, and distribute that executable as if it didn't
include a copy of libcygwin.a linked into it. Note that this does
not apply to the cygwin DLL itself. If you distribute a (possibly
modified) version of the DLL you must adhere to the terms of the
GPL, i.e. you must provide sources for the cygwin DLL.
See for the precise Open Source Definition referenced above.
