is three any coroutine library works in cygwin?

is three any coroutine library works in cygwin?

[echo]

My program is using coroutine(implemented with ucontext api) on linux, I 
am trying to port it to windows using cygwin. But I find out that cygwin 
doesn't support ucontext api, so is there any coroutine library works 
fine in cygwin?

The qemu project has several alternative implementations for coroutines
- in addition to ucontext, it provides sigaltstack, gthread, and win32
implementations.  Perhaps one of those can be used as a starting point
for your needs?  (see the coroutine-*.c files in
http://git.qemu.org/?p=qemu.git;a=tree)

Cygwin 2.0 comes with improved ucontext handling in case of calling
signal handlers.  We might be able to come up with the missing functions
(getcontext, setcontext, makecontext, swapcontext, sigaltstack) at one
point, but that requires some hacking.

Patches are very welcome!

Thank you very muuch, Eric. I will check it out.

I have another problem when I try to subscribe this mail list. I recevei 
a confirm mail from cygwin-help@cygwin.com which require me reply a 
message to

  cygwin-sc.1430402984.ioahhmmolhnlonjaaoaa-fatmck=163.com@cygwin.com

I replied to this address, and nothing happens, it seems that I am not in the mail list.  What should I do to solve this?
