Subject: Fix a warning under gcc
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=30418a3cfcdcdd4195e8f87c656dd0106f8ff9e5;hp=cb1709ef5e6f96d8db44854b42b67fb524214717

Fix a warning under gcc

Locals left and right shadow two same named
variables in the std::ifstream base class.

No functional change.
