Comment:

 Sure. I had a branch, just forgot to submit it.
 I've rebased it onto the current git head and got the merge working
 properly.
 It's a little old, so let me know if there's anything missing.

 '''Branch:''' karsten_bug13192_026_03_teor
 '''Repository:''' https://github.com/teor2345/tor.git

 Just to be clear, what the patch does is:
 * replace `values.h` with `float.h` (do all our platforms have `float.h`,
 or will some need `limits.h`?)
 * change the two lines with `((int64_t) -1) << 53` to `((uint64_t) -1) <<
 53` to avoid undefined signed left shift behaviour

 There was no need to remove `UTIL_TEST(strclear, 0)` from
 `src/test/test_util.c` because the function is present in the file.
