Yes, when linking against the Cygwin DLL there are GPL issues.

But that wasn't what "cyg Simple" was referring to.  The Cygwin distro
comes with a Mingw-w64 cross compiler and libs.  When you use those to
create Mingw binaries, you are not linking against the Cygwin DLL.

So, as "cyg Simple" wrote, there's no reason that you can't use the
Cygwin distro as environment to build non-Cygwin binaries.

There's also the fact that the aforementioned mingw.org project is
rather behind.  The Mingw-w64 fork (which is used by Cygwin as well,
incidentally) is more up to speed in terms of WIndows lib and header
file support.
