grasp it and I can't.

It is exposed if -std=c11 but not for c++11.

No, it's not, you get an implicit function declaration warning in C. C++ is simply less forgiving (which is not a bad thing in this case).

What is the problem and can it be solved?

Use -std=gnu++11, or -D_DEFAULT_SOURCE with -std=c++11.

Why does -std=c++11 prevent POSIX visibility?

Because it means ISO standard C++, which popen is not.

MinGW exposes popen as _popen, could it be an option for Cygwin?

Absolutely not, that is an MSVC-ism.
