I see. I'm attaching the patch for IRIX 6.5 (IRIX64 nut 6.5 07121149 IP27=
):

I've only set the UInt64 support because I don't know if this platform
supports floats of 128 bits and neither what LP64 exactly means.

With that, numarray supports UInt64 arrays on IRIX perfectly:

nut 435$ python
Python 2.2.2 (#2, Nov 19 2002, 18:46:18)
[GCC 2.95.2 19991024 (release)] on irix646
Type "help", "copyright", "credits" or "license" for more information.
>>> import numarray
>>> numarray.ones((3,), numarray.UInt64)
array([1, 1, 1], type=3DUInt64)
>>> ^D

Thanks for the pointer,
