[pdftex] adding pdf-anchors

[Victor Ivrii]

hyperref inserts in pdf file a lot of anchors: at equations, sections,
tops of the pages etc no matter if one labels them or not.

Is there any reqular way to put an anchor into an arbitrary place?
Placing \label{XYZ} does not work: \ref{XYZ} returns the value of the
smallest division/environment, containing the place (say
\thesubsection) and leads to the anchor associated with this
division/environment.

Thank you in advance
