Yes: this is what allows you to use dtype to parse complex binary files
directly in numpy without having to care so much about those details. And
that's how it is defined on windows in any case (C standard only forces you
to have sizeof(long double) >= sizeof(double)).

Too lazy to check on my vm, but I am pretty sure it is 16 bytes on windows
