Subject: Assume UCI 'nodes' is int64_t instead of int
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=bcbab1937670ca39ddb0a216ff9a787e56b79b3a;hp=d29a68f5854d0b529f2e0447fddcc6a61200c5aa

Assume UCI 'nodes' is int64_t instead of int

UCI specification is not clear on the size of
integers that are exchanged in the protocol, so
instead of a simple int, assume 'nodes' is a
int64_t because we need a bigger size to store
this value in many real cases, especialy with
very long searches.

No functional change.

Resolves #75
