Cygwin is not Linux. It consists of a set of tools commonly found on Linux compiled into MS Windows EXE files that will run in a MS Windows environment. Cygwin does not have its own kernel, and it does not run independently of MS Windows.
If you want to split hairs, because it "emulates the behavior" of a Linux/UNIX system" it is by dictionary definition an emulator. However the common vernacular says otherwise.

An emulator has nothing to do with running an operating system it does not need to run a kernel to be an emulator. If you write software that acts like another pice of software/hardware you are emulating it.
setuid and setgid always return ENOSYS.
link will copy the file if it can't implement a true symbolic link. Currently, symbolic links work, if at all, only under Windows NT.
chown always returns zero.
fcntl doesn't support F_GETLK - it returns -1 and sets errno to ENOSYS.
lseek only works properly on binary files.
That seems like its emulating chown and sybolic links. Anyway isnt cygwin just a few DLL's.

So you could write a linux program for windows and vice versa

Ive just started using qemu in linux, but there is a windows version.
Its a free virtual machine, so like VMware but free.
If the windows version is as good as the linux one, you can simply put in another os boot disk and boot from that within windows, installing the new app either to another partition or to an .img file.
It works well, and would let u run a complete linux distro from within windows.
Personally, I would run a virtual machine from linux and boot windows, rather than run linux in windows. Then you can delete the whole windows partition off ur disk, just have linux and boot the virtual windows on the rare occasion you need it. Ive managed to get windows ME installed in mandrake 10.1 without many problems....

Not sure what inderstry your in but that not the per se to me and i dought anyone else emulation does not have to be vmware etc.. which IIRC is hardware emulation which is desribed in that wikipedia link. You are wrong you are trying to use a broad word to describe one thing hardware emulation al la vmware. Only in the computer world would you have two people debatimng jargon
