Subject: Silence idiotic warning on two's complement of an unsigned
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=d7ef09727acc11c91b4a25b775c7f6d0bf1d37d8;hp=d7ef09727acc11c91b4a25b775c7f6d0bf1d37d8

Silence idiotic warning on two's complement of an unsigned

MSVC gives:

warning C4146: unary minus operator applied to unsigned type,
               result still unsigned

When finds -b where b is an unsigned integer. So rewrite the two's
complement in a way to avoid the warning. Theoretically the new
version is slower, but in practice changes nothing.
