Comment (by gk):

 Replying to [comment:21 gk]:
 > I guess what we can do, instead of building libssp with `build-
 libssp.sh` in a separate step, is to just use the static libraries we
 build for `mingw-w64` anyway.

 That approach is not working very well it seems. I used my `bug_29013`
 branch for `tor-browser` and `bug_29013_v2` for `tor-browser-build`.

 First of all for some reason we need the *.dll as well in the Browser dir
 (I thought ssp got statically linked in) but copying it over results in
 crashes both on 32bit and 64bit versions during start-up.

 More digging is needed here.
