Gcc 4.3 and Header issues

I’m using gcc 4.3.3 version and nowadays i’m trying to write hybrid file transfer system with c++ on Linux.The problem is i used to use some function in c or c++ like strcmp() with including string library but now when i try to compile I’m getting some error like
error: ‘strcmp’ was not declared in this scope
Simple example code
In gcc 4.1 version i can compile this code without any error or warning

but same code can’t compile in gcc 4.3 ,it returns error like

We can solve this error with including cstring library .After that our code is

The other missing headers

If missing	Then include this header
find, for_each, sort	<algorithm>
ostream_iterator, istream_iterator	<iterator>
auto_ptr	<memory>
typeid	<typeinfo>
isalnum, toupper	<cctype>
INT_MIN, INT_MAX, RAND_MAX	<climits>
printf	<cstdio>
atoi, free, rand, exit	<cstdlib>
EXIT_FAILURE	<cstdlib>
strcmp, strdup, strcpy, memcpy	<cstring>

Removal of Pre-ISO headers

Various backwards and deprecated headers have been removed.

If missing	Then include this header
<algobase.h>	<algorithm>
<algo.h>	<algorithm>
<alloc.h>	<memory>
<bvector.h>	<vector>
<complex.h>	<complex>
<defalloc.h>	<memory>
<deque.h>	<deque>
<fstream.h>	<fstream>
<function.h>	<functional>
<hash_map.h>	<tr1/unordered_map>
<hashtable.h>	<tr1/unordered_map> or <tr1/unordered_set>
<heap.h>	<queue>
<iomanip.h>	<iomanip>
<iostream.h>	<iostream>
<istream.h>	<istream>
<iterator.h>	<iterator>
<list.h>	<list>
<map.h>	<map>
<multimap.h>	<map>
<multiset.h>	<set>
<new.h>	<new>
<ostream.h>	<ostream>
<pair.h>	<utility>
<queue.h>	<queue>
<rope.h>	<ext/rope>
<set.h>	<set>
<slist.h>	<ext/slist>
<stack.h>	<stack>
<streambuf.h>	<streambuf>
<stream.h>	<iostream>
<tempbuf.h>	<ext/memory>
<tree.h>	<ext/rb_tree> or <ext/pb_ds/assoc_container.hpp>
<vector.h>	<vector>
