I just compiled for 32 bit, and here the math functions are not available.
Did you compile for 32 bit using llvm_31?
This seems likely to be correct:
#if __WIN32 && !_WIN64
#define LLVM_MALLOC "llvm_malloc"
#define LLVM_FREE "llvm_free"
#else
#define LLVM_MALLOC "malloc"
#define LLVM_FREE "free"
#endif
