--- Comment #9 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
No ICE on 4.[789]:

reynosa:/build/pristine-4_8/gcc$ ./xgcc -B./ main.c s.c  -flto -O -DPR47888
main.c:1:13: warning: type of 's' does not match original declaration [enabled
by default]
 extern char s[1];
             ^
s.c:1:14: note: previously declared here
 struct S { } s;
              ^
This only seems to be a problem on 4.6.  Can we mark this as so?
