[SciPy-dev] 32bit vs 64bit doctest differences

It appears that numpy prints the 'dtype=intXX' part only when the size
of int differs from the machine word size.  For example, consider the
following test run on a 64-bit machine:

File "/usr/lib/python2.5/site-packages/scipy/stsci/convolve/Convolve.py",
line 295, in scipy.stsci.convolve.Convolve.boxcar
Failed example:
    boxcar(num.array([10, 0, 0, 0, 0, 0, 1000]), (3,),
mode="wrap").astype(num.longlong)
Expected:
    array([336,   3,   0,   0,   0, 333, 336], dtype=int64)
Got:
    array([336,   3,   0,   0,   0, 333, 336])


Should we just use dtype=int to avoid this issue?  It appears
dtype=int chooses the native size.
