* Suggestion how to "solve" the XML-reading problems in certain environments:

A workaround has been implemented where it is not tried any more to "directly
  parse the file" but rather the file is read into a memory buffer which then
  is parsed.
  For further information, see MUSR-122.

* Fixed a linking problem when only shared libraries are built on Cygwin
  (introduced with the split-off of libPUserFcnBase).
