[Bug c/17730] New: [4.0 regression] Regression in diagnost message "invalid lvalue in unary %<&%>"

["bangerth at dealii dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This little (invalid) code 
---------------- 
char *p = &'C'; 
---------------- 
produces this diagnostic regression in the C front end: 
 
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/gcc -c y.c 
y.c:1: error: invalid lvalue in unary `&' 
 
g/x> /home/bangerth/bin/gcc-4.0-pre/bin/gcc -c y.c 
y.c:1: error: invalid lvalue in unary %<&%> 
 
Apparently something went wrong during the switch to a better quotation 
style.
