Pearu, thanks for the reminder: the old gcc 3.3 vs 4.0 problem. The good 
news is that switching to 3.3 fixes the machar problem. However, there 
are new failures, at least with the version 1840 from svn.

See further down for another, unrelated problem in linalg.

I will keep this thread going, but also post tickets.

Also, I've found another problem, not in the unittests, with 
linalg.cholesky_decomposition:

/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/numpy/linalg/linalg.py 
in cholesky_decomposition(a)
     127     if results['info'] > 0:
     128         raise LinAlgError, 'Matrix is not positive definite - 
Cholesky decomposition cannot be computed'
--> 129     return transpose(triu(a,k=0)).copy()
     130
     131

NameError: global name 'triu' is not defined

triu() is found in numpy/lib/twodim_base; I suppose this means it's not 
being imported correctly here.


Thanks for the great and quick work to all, especially Travis!
