I must be a bit thick today.  I don't understand why:

- it compiled cleanly under g++ 3.3.1 on FC1, but not 3.3.3 on FC2

- cstring depends on cstdlib being included first and doesn't include it 
itself

- how including cstring will resolve problems with cstring.

- how setting the namespace after the includes will have any effect on 
errors that arise from including header files.

- how this code failed when your test code worked.  I just rearranged 
main.cpp so the first lines read:


#include <cstdlib>
#include <cstring>
#include <iostream>

... rest of the program as before


and the same errors result.  I guess that it is time to dig into the g++ 
options this code is using.
