Subject: Fix a warning with POPCNT and MSVC
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=1ea70dd9ddb346aaa23e592edcff9774c305174d;hp=13c096f839f991c5d0da1d9bf8d95eae6d0c0aa0

Fix a warning with POPCNT and MSVC

Intrinsic __popcnt64() returns an unsigned __int64, cast
to an integer and silence the warning.

No functional change.
