It seems that some BSD systems have bugs in their handling of the  
_XOPEN_SOURCE macro (which is supposed to turn on certain POSIX and OPEN UNIX 
standard behaviors so we can depend on things like thread-safe/reentrant 
behaviors and consistent structure layouts in standard system libraries).  I 
turned that on to get reliable IPV6 data structure layouts and because Solaris 
(and presumably other systems) actually still uses non thead-safe errno by 
default, but it' s triggering this BSD bug on your systems.

I've changed gnustep-base to try using _POSIX_C_SOURCE=199506L instead ... 
which should give much the same effect for turning on standard conformance, but 
might not trigger the BSD bug.
If that also causes problems on your systems, then I guess we'll need to 
develop system specific conditional code to handle them :-(
