Thank you for the patch.  I have a question for you.

https://codereview.appspot.com/6197060/diff/1/nss.gyp
File nss.gyp (right):

https://codereview.appspot.com/6197060/diff/1/nss.gyp#newcode291
nss.gyp:291: 'msvs_disabled_warnings': [ 4133, 4090 ],

If the two warnings in prprf.c are the only instances of
warnings 4133 and 4090, I can fix them in the upstream.

Ah, that would be better. The full set that I see are these:
