 Not really, since it involves setting up an environment where
 sizeof (long) > sizeof (char *). In that environment,
 gcc would crash compiling even trivial "hello, world".
 
 In my case, it was http://www.fw.cz/~mitr/maxos.html
 (snapshot available at http://carolina.mff.cuni.cz/~trmac/MaxOS,
 including patched gcc). If someone would like to reproduce this
 independently, I can dig up the necessary gcc patches (new
 target OS) and create "before" and "after" iso images.
 
 The patch seems obvious to me though ;-)
