In this case, it's kind of rightfully picky - designated initializers like that
is not standard C++ and normally only exist in C. GNU may happen to expose them
as part of their GNU flavour of C++.
If you're using `-std=c++11` or such, try `-std=gnu++11`.
You could also try constructing a `pollfd` object before the statement and
pushing that, or possibly passing `pollfd{.fd = _listen_socket, .events =
POLLIN}`.
You're probably looking at some fun interaction of GNU extensions with the
advent of initializer_list:s in C++11.

Can you share the easyconfig file, so we can try to reproduce this?
It's probably the Intel compilers being a bit picky here, wouldn't be
the first time...
Looks like it may just need some convincing with a cast or something?
My C++ is too rusty to quickly figure this out though...
Maybe this helps:
