There used to be a Cygwin bootstrap.sh script[1] that builds a Cygwin cross-compiler and compiles a native W32 Cygwin with it, but i can't find it anymore (FTP server it was located on had some rearrangements). My sbuild MSYS2 bootstrap[2] is based on it though, so you may as well just use that (i've modified it to build i686 instead of x86_64, but shouldn't be hard to put x86_64 back in). That's all i have. And don't ask me how it works, because to me it's like magic.
