Subject: Fix a warning with __popcnt64() intrinsics
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=04001f776edd312418ad8334f4287b4d1dba5f7b

Fix a warning with __popcnt64() intrinsics

Returns an int64_t while we want a simple int.

This occurs only when compiling with MSVC on a 64 bit platform.

No functional change.
