D.2.14 Modifications de la version 3.22.13

• Saving NOW(), CURDATE() or CURTIME() directly in a column didn't work.
• SELECT COUNT(*) ... LEFT JOIN ... didn't work with no WHERE part.
• Updated `config.guess' to allow MySQL to configure on UnixWare 7.0.x.
• Changed the implementation of pthread_cond() on the Win32 version. get_lock() now correctly times out on Win32!
