I just got hit with that bug and spent too much time figuring out what was
wrong. Here's my code, just to show an example of real-life usage:
//////////////////////////////////////////////////////////////////////////
/**
* Returns the unsigned version of \a number.
*/
template< class T >
T abs( T number )
{
// This is the default implementation, using comparison to zero and unary
// negation operator.
if ( number < 0 ) {
return -number;
}
return number;
}
// Here are some specific implementations.
template<> bool WRAP_API abs( bool number );
template<> char WRAP_API abs( char number );
template<> unsigned char WRAP_API abs( unsigned char number );
template<> short WRAP_API abs( short number );
template<> unsigned short WRAP_API abs( unsigned short number );
template<> int WRAP_API abs( int number );
template<> unsigned int WRAP_API abs( unsigned int number );
template<> long WRAP_API abs( long number );
template<> unsigned long WRAP_API abs( unsigned long number );
template<> float WRAP_API abs( float number );
template<> double WRAP_API abs( double number );
//////////////////////////////////////////////////////////////////////////
Please fix this bug!
