yes, but: That is part of the up-coming C++0x standard (just read the
file basic_string.h a file lines before:
#if (defined(__GXX_EXPERIMENTAL_CXX0X) && ....)
So: You have to tell g++ to compile your code using the standard C++0x;
if not, he ignores those lines.
That's done by adding the option "-std=c++0x" when you call the
compiler.
With that, your code compiles and runs (after adding a missing ";" in
your example ;-)) here.
I tried it on g++ 4.6.0 (20100916), but your compiler should also be
modern enough (as you have already the necessary functions in your
header files).
HTH,
Axel
