Comment (by KSHawkEye):

 A possible solution can be found here:
 http://sourceforge.net/mailarchive/message.php?msg_id=28070146

 Here is a patch that can fix the issue but I have '''NOT''' been able to
 test if this breaks the build for Linux.

 I'm open to a different solution to this problem, but would really like to
 get this bug closed.
