>Description:
It seems like the depr.c.header string.h is sometimes 
(but not always) wrapped inside namespace std.  This should
always happen to the cstring header, but never to string.h,
according to ISO/IEC 14882:1998, Annex D, secton 5.  This
code does not compile, thus exhibiting the problem:

#include <iostream>
#include <string.h>

int main(void)
{
	const char * a = "ll";
	const char * b = "hello";
	if (::strcmp(a,b))  // changing to std::strcmp works.
		printf("yes\n");
	else
		printf("no\n");
	return 0;
}

Also, I noted that reversing the two include directives seems 
to fix the problem.
