Subject: Add some explicit casts as needed to make ed25519_ref10 compile
X-Git-Tag: tor-0.2.6.1-alpha~87^2~20
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8594e97c0350abb2a0214c848b712e6e68cde3e5;p=thirdparty%2Ftor.git

Add some explicit casts as needed to make ed25519_ref10 compile

Apparently, ref10 likes implicit conversions from int64 to int32 more
than our warnings do.
