I feel sorry for...

The people credited with bringing GNUstep support to OCUnit a few versions back (at least one of whom I recognise as a competent programmer who really knows what they're doing), as the current version just won't work at all ;-).  It'll be more future-proof on the Apple platform, as it uses @try/@catch blocks.  However, as I want to use it on the GNU platform, this means a lot of #ifdef __NEXT_RUNTIME__ wrappers and NS_DURING/NS_HANDLER/NS_ENDHANDLER blocks...
