  the event waited in SCardGetStatusChange() occurs.

Explanation of the Ubuntu delta:
  * Merge new upstream release from Debian Unstable (LP: #1483750).
    - debian/rules: Move runtime libraries to /lib, for the benefit of
      wpasupplicant. (See Debian #531592)

Sorry, my packaging skills are zero, so that I can't work on this merge.
