The C++ standard defines the C headers such as <string.h> and <wchar.h> in
terms of their C++ versions such as <cstring> and <cwchar>, which in turn are
defined in terms of the headers in the C standard.
Thus, <string.h> and <wchar.h> require the function overloads for functions
such as strchr and wcschr that are defined to be in <cstring> and <cwchar>.
However, libstdc++ defines these only in <cstring> and <cwchar>, not in
<string.h> and <wchar.h>.
libstdc++ needs to wrap the headers provided by the C library, or otherwise
cooperate with glibc and other C library implementations, to get the required
C++ definitions in place.
This is different from bug 6257, and unlike that bug this one appears still to
be a bug with the current C++0x draft.

------- Comment #1 from pcarlini at suse dot de 2007-10-29 01:09 -------
Yes, in some sense the resolution of DR 456 doesn't consider strchr and co.
Some time ago I mentioned that in private email with Howard but then didn't
really pursue it. Will do, maybe at one of the next C++ meetings.

This is really the same as libstdc++/30928.

Let's keep this one open instead, as a reminder that the libcs of non-GNU
targets have to provide a mechanism similar to the one used by recent glibcs:
http://gcc.gnu.org/viewcvs?view=revision&revision=143773
and which we can exploit in the C++ library.
