Determine terminal size on MinTTY and Cygwin

[adammurdoch]

Any hint on what's left to do to resolve this? According to the code at mintty/mintty#1071, calling ioctl(1, TIOCGWINSZ, &ws); should work to get the number of rows / columns. And as there already is

native-platform/native-platform/src/main/cpp/posix.cpp

Line 374 in 8a0dc39

int retval = ioctl(output + 1, TIOCGWINSZ, &screen_size);

I'm wondering whether it shouldn't "just work"?
