Please sync wvstreams 4.6.1-2 (main) from Debian unstable (main) was: wvstreams version 4.6.1-1ubuntu1 failed to build in oneiric

Description:
Please sync wvstreams 4.6.1-2 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
Ubuntu changes are all incorporated in Debian and the new Debian
revision fixes the FTBFS.

Changelog entries since current oneiric version 4.6.1-1ubuntu1:

wvstreams (4.6.1-2) unstable; urgency=low

  * QA upload.
  * Switch to format 3.0 (quilt).
  * debian/patches/05_gcc.diff:
    - Fix FTBFS with new gcc (Closes: #621990).
  * Drop obsolete Conflicts/Replaces fields.
  * Bump Standards-Version to 3.9.2.
