[svn] commit: r3905 - /trunk/src/lib/asiolink/internal/udpdns.h

[BIND 10 source code commits]

New Revision: 3905

Log:
defined UDPQuery::~Callback explictly, making it virutal in order to avoid getting the "non-virtual destructor" warning from a certain version of gcc.
It caused buildbot failures, and I confirmed the fix on sol-10.lab, so committing it to trunk directly without having an explict review.
The fix should be quite trivial.
