[PATCH 11/12] compat/nedmalloc/malloc.c.h: fix compilation under MinGW-W64

From: Marat Radchenko <marat@slonopotamus.org>

Message-ID: <1398762726-22825-12-git-send-email-marat@slonopotamus.org>
In-Reply-To: <1398762726-22825-1-git-send-email-marat@slonopotamus.org>

1. Unlike MinGW, MinGW-W64 already provides _ReadWriteBarrier macro,
   so don't try to redefine it.

2. MinGW-W64 has a strange definition FORCEINLINE as
   extern __inline__ __attribute__((__always_inline__,__gnu_inline__))

   'extern' doesn't work together with 'static', so #undef MinGW-W64
   version of FORCEINLINE.
