[PATCH] ntfs-3g needs OpenBSD specific groupmember() function

Hi Ports,

I have an upcoming patch to FUSE that passes the current process tid,
uid, gid and umask to the file system. This has highlighted a bug in the
port where the groupmember() function in libntfs-3g/security.c assumes
it's runing on Linux where thread information is available in /proc.

This diff adds an OpenBSD specific implementation of this function.
