Use GlobalMemoryStatusEx() for more consistency across NT platforms.


unsigned long co_os_get_physical_ram_size( void )
        {
        MEMORYSTATUSEX            m ;

        m.dwLength = sizeof( m ) ;
        GlobalMemoryStatusEx( &m ) ;
        if( m.ullTotalPhys > (DWORDLONG) 0xFFF00000 )
                return 0xFFF00000 ;
// avoids 64bit to 32bit overflow conversion
        return 0xFFF00000 & (unsigned long) m.ullTotalPhys  ;
        }
