Comment(by datallah):

 I uploaded an updated patch that links libssp statically into both
 pidgin.exe and libpurple.dll - everything else is linked to libpurple.dll,
 so that's all that is necessary.  Ideally we'd ship libssp-0.dll and link
 it dynamically, but I don't see an easy way to grab the dll during the
 packaging process.

 It isn't clear to me what the benefit of using `-fwrapv` is, and I don't
 even see `-fno-strict-overflow` documented in the gcc documentation at
 all.
