Bad volatile -mstrict-align code on powerpc on 4.0.2?

[Peter Dufault]

Can someone sanity check this and verify that I'm not doing anything  
stupid?  This is gcc 4.0.2 compiled on solaris 10.  It is generating  
wacky code with -mstrict-align unless I'm doing something dumb.  In  
the following script it is generating reasonable code without - 
mstrict-align, when I turn on -mstrict-align it is amoungst other  
things reading back from the volatile register before writing to it.   
Is there another attribute I'm supposed to use?
