Hi,
> are there know issues with select() when build for MinGW ?
Yes.
1) In https://lists.gnu.org/archive/html/bug-gnulib/2016-12/msg00112.html
you can see that we have known test failures.
2) Gnulib's implementation of select() cannot look at the sockets at the
non-sockets (files and pipes) at once; therefore it uses an alternating
approach, which means that in the worst case, it can busy-loop.
3) I also recall that the case of pipes is not working 100% fine.
I wish someone who has time could look into it again...
