Comment:

 Okay, this move breaks the build. It turns out, there is a bunch of files
 where _vsnprintf_s is used/needed and there are other secure functions
 deployed as well (like _vsnwprintf_s). That probably amounts to a lot of
 patching. :-/ And disabling the secure API for all Windows users is not
 funny either. Are there any other things we could do here? Asking the
 affected users to get a newer msvcrt? Or bundling a newer crt with the Tor
 Browser? Something along the lines: "If you intend to distribute your
 build to others, you will need to set
 WIN32_REDIST_DIR=$VCINSTALLDIR\redist\x86\Microsoft.VC80.CRT in your
 mozconfig to get the Microsoft CRT DLLs packaged along with the
 application." as mentioned on https://developer.mozilla.org/en-
 US/docs/Developer_Guide/Build_Instructions/Windows_Prerequisites maybe?
