TYPO3 Core

Also applies to 4.0.5 and should really be fixed

What exacly is this setup? The behaviour in 4.0x is expected to have all anchors prefixed with a "c" (else it won't be XHTML conform!).

Any typolink that generates a section mark in 4.0.x will generate a "c" prefix. So it should work if you:

Upgrade and stop using the "old" css_styled_content and just use the "new" css_styled_content that comes as a sysext in TYPO3 4.0. Any "hardcoded" section links that you have will be modified manually. Links that come from RTE (<link pid#uid>) will be rendered correctly, because the new parseFunc_RTE also uses typolink which will prefix the anchor with "c".

So you have to be more specific or do some research on what exactly fails and how we can fix it.

No feedback, so problem probably disappeared.
