[issue12852] test_posix.test_fdlistdir() segfault on OpenBSD

[Charles-François Natali]

> I think that the problem is that fdopendir() is not defined. If a function is not defined, C uses int as the result type. An int is not enough to store a 64-bit pointer. See in gdb output: dirp is 0x0afb0e80 whereas other pointers look like 0x20973fc30. You missed the highest hexa digit (0x2).

Yeah, I noticed that. I didn't make the connection with the
possibility of missing prototype though. Nice catch.

You mean that the patch you attached doesn't work, correct?
I know it's a stupid question, but you're sure you didn't forget to
run autoconf/autoheader?
