Actually I had some spare time yesterday so I came up with an
implementation of posix_spawn_file_actions_addchdir_np and
posix_spawn_file_actions_addfchdir_np.  It's pretty straightforward:

https://cygwin.com/cgit/newlib-cygwin/commit/?id=7e03fc35f528
https://cygwin.com/cgit/newlib-cygwin/commit/?id=c743751aafa8

You can install the just building test release
cygwin-3.5.0-0.287.g53f7fb20a064 via our installer, if you'd
like to test it.

Actually... do you have a testcase readily available to share with us?


Thanks,
Corinna
