Subject: Only use _ReadWriteBarrier on MSVC
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=7b4828b68ced7e92a3399f9e48da8726b6b315f0;hp=f6d220ab145a361f7240a44dbe61056e801d9bda

Only use _ReadWriteBarrier on MSVC

It was causing compile errors when cross-compiling using mingw.

No functional change.
