c++0x won't let me use 'putenv'?

[DrEvil]

So lately I have been including various c++0x methods in my code.
Yet I try and use putenv and apparently "was not declared in this scope" although I have included both "iostream" and "cstdlib".
Which when the compiler flags don't have c++0x language standard it doesn't provide an error and compiles.

CodeBlocks 10.05
Project-> Build Options-> Compiler Flags-> "Have g++ follow the coming c++0x standard..."
I believe this is the correct way to include c++0x methods for CodeBlocks.

I have scanned the c++0x page but nothing states any environment variable changes :s

Anyone received this problem? Know anything?

Maybe it just allows the syntax but doesn't support it yet..

Like, it can parse it but it hasn't been implemented.
How can I explain.. Uhh..
