Subject: Fix compile for some versions of mingw
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=0edb6348d20ec35a8ac65453239097078d947b7e;ds=sidebyside

Fix compile for some versions of mingw

The bswap intrinsics are specific to the compiler, not the
host platform.

No functional change.

Resolves #155
