Hello,
I just bought _Nim in Action_ a few days ago and was following the ChatApp
exercise and couldn't compile the clients.nim on Windows. It looks like when I
import asyncdispatch
and compile it with _\--threads:on_ I get _error: redefinition of 'struct
ip_mreq'_. I think the problem can be fixed by reorganizing the #includes in
the generated **nimcache\stdlib_asyncdispatch.c** to the way the answer
suggests on
[https://stackoverflow.com/questions/1372480/c-redefinition-header-files-winsock2-h](https://stackoverflow.com/questions/1372480/c-redefinition-header-files-winsock2-h)
it will work, but I'm not familiar with the process.
