What PHP version is supported by which TYPO3 release?

Question

I'm planning on upgrade my PHP to version 5.3. Most of my sites are running on the TYPO3 framework. Some of this have an install before TYPO3 version 4.5. Are there any known issues of older TYPO3 versions and PHP 5.3?

I can't find anything about system requirements for this older TYPO3 versions.
