Oh what fun it would be: a compiler with useful error messages

the code:

#include "common.hpp"

template<typename ACHAR>
class GameException
: public std::exception
GameException() throw();
GameException(const ACHAR*) throw();
GameException(const basic_string<ACHAR>&) throw();
virtual ~GameException() throw();
virtual const ACHAR* what() const throw();
const ACHAR *why;

the error:

s:visual studio 2008projectstacfpsgameprojectnamesourceincludegameexceptions.hpp(17) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

the solution:

fully qualify basic_string<> as std::basic_string<ACHAR>, or add ‘using std::basic_string’ to common.hpp along side std::string and std::wstring, like I thought I did last week !!!

simple fact: compiler errors usually suck, and C++ templates don’t help any.
