Does CMS 1.6.1 work with PHP5.3?

[frodeaux]

Does the latest (1.6.1) release support the now released PHP5.3?

I've upgraded to PHP5.3 because of another, non-CMSMS project and
have run into a problem an existing CMSMS 1.5.4 based project that
has come up after my upgrade.  Will upgrading to CMS 1.6.1
handle PHP5.3?

The problem looks like this:

CMSMS is including/requiring "function.Title.php" and as "function.title.php"
two different files.
This on OS-X whose file system is case-preserving but not
case sensitive.  Looks like PHP5.3 has different rules for
recognizing when include_once is given the same file name.
