+NOTE FOR MacOS X PLATFORM
+-------------------------
+
+Many versions of yasm/nasm are known to be buggy for Mach-O output.
+Whereas nasm seems to be less reliable than yasm. Therefore, yasm
+is highly recommended for Mac OS X target.
+
+* yasm 0.7.99.2161 or later is required for Mac OS X build. *
