D.3.32 Modifications de la version 3.21.4

• Should now configure and compile on OSF1 4.0 with the DEC compiler.
• Configuration and compilation on BSD/OS 3.0 works, but due to some bugs in BSD/OS 3.0, mysqld doesn't work on it yet.
• Configuration and compilation on FreeBSD 3.0 works, but I couldn't get pthread_create to work.
