Because the C runtime startup files expect that your code has a main()
function.

You appear to be trying to do *nix type syscalls.  That won't work. 
Windows does not use int 80 to call into the kernel.  If you are trying
to follow some kind of assembly language tutorial for linux or BSD then
you'll need to actually run this on a linux or BSD system.  Cygwin
provides compatibility on an API level only, not at the level of
syscalls.
