perl 5.10.0 dies if -C occurs on the #! line. This was to avoid the  
problem of the options being present but not doing anything (see  
#34087). But this breaks many existing programs that were relying on  
the kernel to read the first line and pass the switch to perl.

The attached patch changes perl to die only when the #! switch differs  
from the command line switch.

Since this is a 5.10 regression, is there any chance it could make its  
way into 5.10.1?
