undeclared memcpy() in flex_string.hpp

[farid_zaripov]

I have been working on the Apache C++ Standard Library project (STDCXX):
http://incubator.apache.org/stdcxx/

I've trying to compile the boost library with stdcxx.

The details can be found here:

Boost version: 1.33.1
STDCXX version: 4.2

I've got the error in boost/wave/util/flex_string.hpp:

D:\_Libs\boost_1_33_1\boost/wave/util/flex_string.hpp(126) : error C3861: 'memcpy': identifier not found

I propose to #include <string.h> in flex_string.hpp file to declare memcpy().

In addition I have compiled boost with stdcxx on gcc 3.4.4 / Cygwin and got the following errors:

---------------------------------

I propose to #include <cstdlib> to declare malloc() and #include <new> to declare bad_alloc.
