I've asked a C++ standards guru and adding to namespace std is undefined
behaviour. From the C++11 standard section 17.6.4.2.1:
" The behavior of a C++ program is undefined if it adds declarations or
definitions to namespace std or to a
namespace within namespace std unless otherwise specified"
However the WinCE build needs to use STLPort anyway for the
implementation of the std namespace. STLPORT does a #define on "std" so
this should all be ok. I'll let you know once I've tried it and updated
my branch if it does work.
Regarding the struct vs. class, there's a question on Stackflow about
what the standard says, which seems to conclude that it shouldn't matter:

The important part though is that the name mangling that Visual Studios
does uses 'U' to mean struct and 'V' to mean class (
http://en.wikipedia.org/wiki/Microsoft_Visual_C%2B%2B_Name_Mangling#Data_Type).
