I'm not certain, since I don't have VC++, but I believe
#if defined(_MSC_VER) && defined(WIN32)
#define rotate_left(a,n) _lrotl(a,n)
#define rotate_right(a,n) _lrotr(a,n)
#else
#define rotate_left(a,n)
(((a)<<(n&0x1f))|(((a)&0xffffffff)>>(32-(n&0x1f))))
#define rotate_right(a,n)
(((a)<<(32-(n&0x1f)))|(((a)&0xffffffff)>>(n&0x1f)))
#endif
should work.
