New issue 3144: pypy3.6 7.3.0 curses get_wch: ffi.error: undefined type name wint_t[1]
https://bitbucket.org/pypy/pypy/issues/3144/pypy36-730-curses-get_wch-ffierror

Anthony Sottile:

Still reproduces on the latest nightly – seems to be a regression \(I was able to call this function previously, it just misbehaved\)

‌

```
$ ./pypy-c-jit-98442-def680385695-linux64/bin/pypy3 ../t.py 
Traceback (most recent call last):

    wch = ffi.new("wint_t[1]")

```python
import curses

def c_main(stdscr):
    stdscr.get_wch()

curses.wrapper(c_main)
```

In case it matters, here is my curses versions:

```
$ dpkg -l | grep libncurses
ii  libncurses5:amd64                          6.1-1ubuntu1.18.04                              amd64        shared libraries for terminal handling
ii  libncursesw5:amd64                         6.1-1ubuntu1.18.04                              amd64        shared libraries for terminal handling (wide character support)
ii  libncursesw5-dev:amd64                     6.1-1ubuntu1.18.04                              amd64        developer's libraries for ncursesw
