On Windows (32 bits and 64 bits) the size of both int and long is 4 bytes, so the cast should be fine: http://software.intel.com/en-us/articles/size-of-long-integer-type-on-different-architecture-and-os/ http://msdn.microsoft.com/en-us/library/aa383751%28v=vs.85%29.aspx
This aside, in case you missed them i sent three updated patches yesterday (Not numbered this time) and one a week or so ago that fixed a problem regarding folder creation with make checkheaders.
