My experience of using VC7.1 is that having wchar_t as a typedef for unsigned
short (which is the default) causes problems with overloading. e.g.

void doStuff(char);
void doStuff(wchar_t);
void doStuff(int);

unsigned short x;
doStuff(x); // picks wchar_t overload if /Zc:wchar_t is not enabled
            // int overload if it is.

So therefore you really want /Zc:wchar_t enabled for all projects.
