Programs built for Linux don't > include any gnu code (libc is a shared library), This is not quite true: programs built for Linux *do* include GNU code, even though libc is a shared library. In particular, they include code from libgcc.a and from crt*.o. It's just that this code is covered by special exceptions which mean that programs which include this code don't have to be licensed under the GPL. > If you link a Linux program statically, > then you'll have the same problem with Linux as you do with Cygwin. No, you won't. You must abide by section 6 of the LGPL, which means among other things that you need to provide relinkable object code, but you don't need to provide source code. -- Fergus Henderson | "I have always known that the pursuit WWW: | of excellence is a lethal habit" PGP: finger fjh@128.250.37.3 | -- the last words of T.
