I'm planning to upgrade one of my servers from RELENG_5_2 to RELENG_5_3.
In my reading of /usr/src/UPDATING I have reached the entry of 20040728
which says that all programs written in C++ need to be recompiled. Ugh.
Is there an easy way to find out whether particular port uses C++? I had
a quick look at bsd.port.mk but didn't see anything.
The ports I'm most interested in are apache2, mod_php4, mysql40-server,
postfix and cyrus-imapd.
Or should I more or less expect that I need to rebuild *all* the ports
