Open a PR and CC Gabriel. I am sure he will give his opinion as soon
as he has free time. Otherwise, this may get forgotten. As I guess, I
think that if ISO C++ forbids the comparison, this should be a
pedwarn. On the other hand, this may be some special case as these
ones:

cd ~/src/trunk/gcc/cp/
grep -n -e "error (.*ISO C\+\+" *.c /dev/null
decl.c:4232: error ("ISO C++ forbids use of initializer list to "
decl.c:6835: error ("ISO C++ forbids in-class initialization of non-const "
decl.c:9753: error ("ISO C++ prohibits overloading operator ?:");
typeck.c:3360: error ("ISO C++ forbids comparison between pointer
and integer");
typeck.c:3365: error ("ISO C++ forbids comparison between pointer
and integer");
typeck.c:5575: error ("ISO C++ forbids casting to an array type %qT", type);

Cheers,

Manuel.
