Squirrelmail and PHP6

This has come up on IRC a few times in the last couple of days, and I
figured it should be mentioned here as well.

PHP6 is making some major changes in terms of removing old
functionality that will have a big impact on Squirrelmail.  Most of
the changes are being tagged as deprecated in the 5.3 series.  Some
items have already been mentioned on the list, such as removing
session_unregister.  This article contains a fairly complete list of
the changes:

The big changes that I've noticed are removing of ereg from a stock
PHP build and dropping support for the PHP4 object model.  Ereg is
used pretty extensively in SM.  PHP4 objects are also used throughout
for message delivery, i18n/l10n, and templates in DEV.  I don't know
what behavior 5.3 exhibits with a PHP4 object, but we know it will be
dropped in PHP6.

Just wanted to make others aware of the coming doom. ;)
