Try to fix BUG #2599
Not sure if this is a good way to go about it, but it seems to work.

Might be good to get rid of all the INT64_MAX/MIN stuff in parser.pyx and replace with np.iinfo(np.int64).max/min instead.

I'm pretty sure this is a Cython bug also and should be reported separately
 Agreed, i will file something with them.  However, I find it appealing to rely on numpy to provide the min and max values for the different dtypes rather than having to rely on stdint.h.   I think i should be able to eliminate the use of any of the stdint stuff from parser.pyx.  Would that be helpful or would you rather scrap the change altogether?
 Merged and verified this fixes the issue. Thanks dieter
