dpi/downloads.cc patch

Hello all,

I have been away for a bit, and had to catch up with some of the mail
on the list.  Looks like you are moving things along quite nicely!

I built the latest version, and I can confirm that Jorges patch for
the search dialogue seems to be working nicely.  When I built it
though, I got a warning from Clang.  The following seems to quiet the
warning in Clang, and does not seem to generate any issues with gcc
for the compile:
