[Bug c/27676] New: gcc is overly strict in assignment to read-only data

gcc refuses to compile this admittedly completely useless code:
int main(void) {
if(0) "hello"[0] = 'H';
return 0;
}
with
bug.c: In function ‘main’:
bug.c:2: error: assignment of read-only location
Obviously, this assignment will cause problems if it is ever executed, and a
warning is a good idea, but it is allowed in C if it will always be skipped, so
it should not be a hard error.
This happens with any compiler option I could think to try (including -ansi). I
can see this with gcc 4.0.3, gcc 4.1(20060517) and gcc 4.2(20060513).
