Hi,

insighttoolkit4 FTBFS on powerpcspe[1] like this:

This is because of WORDS_BIGENDIAN (which is either defined or not) used as
"#if WORDS_BIGENDIAN". The attached patch fixes this by using #ifdef instead
(as in the other places in the package). This is definitely an upstream bug,
and not very powerpcspe related at all.

Unfortunately, after applying this fix, the build runs amok by printing:

"""
**********************************
truth values: Initialize
truth values: GetValueAndDerivative
truth values: Iterate over region
* Testing with identity transforms...
Check Value return values...
--Number of threads used: 1
"""

much later on in an infinite loop. This needs to be investgated separately.

I'm filing this patch just because it might be useful anyway.

Thanks,

Roland
