Windows (from Win 98 and above) has Fibers which provide this
functionality. There's a convenient API for doing all the coroutine type
stuff.

The 'Io' programming language (http://www.dekorte.com/Software/C/Io/) has
support for coroutinues by playing around with the setjmp buffer to
provide a new stack and starting address. I ported this to Symbian
without difficulty and it has support for Windows, Linux and FreeBSD I
believe.
