It would be somewhat difficult to detect the bug, as it is by its very nature 
random. In fact, it is never seen with gcc 4.2.4, despite the fact Sun 
acknowledge it is a bug on Solaris - the upper 32-bit of a 64-bit register are 
not set to 0 as they should be. So I'd rather warn the user. In any case, if 
they build it on sun4v, it could be put on another sun4v machine, where the bug 
does exist. (Sun will soon have a patch for it).

So is there a way I can check the architecture? Also, I would like to know if 
the machine is sun4m, as that can not be upgraded to Solaris 10. Since Solaris 
10 is the only supported version of Solaris, and earlier (sun4m) hardware can 
not be upgraded, I would like to be able to test the architecture.

Any, that aside, how could I use the output of any arbitrary command, to return 
something I can test on?
