The new check-installed-headers rule check now complains with C++
comment from string3.h with:

../string/bits/string3.h:129:1: error: C++ style comments are not allowed in ISO C90
 // XXX We have no corresponding builtin yet.

Let use old C style comment to make compiler happy in old modes.

Tested on x86_64.

	* string/bits/string3.h: Remove C++ style comments.

Good catch, bug report created [1].  I will work on it.
