[tex4ht] [bug #607] tex4ht with package hyperref and option destlabel creates no ancor

[Ulrike Fischer]

Sorry I didn't really follow, but in PDF the destlabel option of hyperref works with a two-pass compilation: 
at the first compilation, the destination in the PDF has the normal name (e.g. section.1), and when the \label is seen, hyperref stores into the aux the new name:

\hyper at newdestlabel{section.1}{special-sec-label}

At the second compilation, hyperref then replaces "section.1" by "special-sec-label".

I don't quite see why it should be difficult for tex4ht to use the info from the aux too.

> In PDF, it may be possible to insert the destination on the same line, because
