[imp] PHP 4.3.0 Appears to break IMP

[Joe Jenkins]

Just a fair warning, PHP 4.3.0 changes in PEAR I believe are enough to break
the IMP module of Horde.  I tried updating last night but ended up rolling
back to 4.2.3 to get it to work properly again.

Recieved this in my logs:

[Fri Dec 27 20:32:13 2002] [error] PHP Warning:  Unknown(): Your script
possibly relies on a session side-effect which existed until PHP 4.2.3.
Please be advised that the session extension does not consider global
variables as a source of data, unless register_globals is enabled. You can
disable this functionality and this warning by setting session.bug_compat_42
or session.bug_compat_warn to off, respectively. in Unknown on line 0
