This is the not working code:

log_type &operator++ (log_type &aLogType)
{
     aLogType = (log_type)++((int)aLogType);
     return aLogType;
}

Compiling...
client_db.cc
C:\work\nt-3.0\src\client_db.cc(163) : error C2105: '++' needs l-value
Error executing cl.exe.

This works:

log_type &operator++ (log_type &aLogType)
{
     int i = (int)aLogType;
     aLogType = (log_type)(++i);
     return aLogType;
}

Regards

Guido
