I really hate to step into any messy legal conversation, but...

I think you might have misunderstood what the OP described, and your wording above may be misleading. >From the limited description given, it sounds as if 1 was meant to be a Linux emuation environment for in-house development. If the only product ever released is a Linux one, not a Cygwin/Windows one, there is no problem. If 2, 3, and 4 are only done in-house and not packaged as part of a product, there is no problem. Even if they are packaged as part of a product, as long as the exact sources used to build the binaries are provided (or a written offer for such valid for three years yada, yada, yada...), there is still no problem. > If you want other arranagements then you do have to pay for that. > > But, the lawyer advice is still sound.
