The test is still buggy on mingw; here's a followup for the test to at
least let it compile, and I'm still investigating why the test fails on
mingw (but it looks like the problem is in:
156 orig_stdin = dup_noinherit (STDIN_FILENO);
(gdb) n
(null): _open_osfhandle failed: Bad file descriptor
when stdin is closed - dup_noinherit needs to silently ignore this failure).

I'll see if I can reproduce that, and if so, figure out why Linux was
happy when cygwin wasn't.
