All the patch does is check to see whether the *input filename* is 
the same as the intermediate filename it wants to use only when 
-save-temps is in effect.  If it is, it generates the temp file it 
would have generated if -save-temps was not in effect.  No other 
behavior is being affected.  If the user compiles a foo.c with -S and 
also has a foo.s then, yes, it is still going to be clobbered with 
the new foo.s.
