I encountered this issue as well on Cygwin. The problem is Cygwin 
defines int32_t and uint32_t
as longs instead of ints. A quick hack to get LLVM building is to edit 
/usr/include/stdint.h and change
typedef long int32_t to typedef int int32_t, and the same for uint32_t. 
The proper fix would be to
update the source to eliminate the ambiguities which occour when int32_t 
is defined like this. I did
intend to do this and send in a patch but haven't got around it yet.
