Odd.  UnitKit in the √Čtoil√© repository installs correctly.  That symlink should 
be created by [g]make install...

objc_msgSend() is an implementation detail of the NeXT and Apple runtimes.  It 
is not possible to implement in a portable fashion, so the GCC and GNUstep 
runtimes use a different approach.  For portable code, use 
class_getMethodImplementation() and then call the returned function.
