I thought we had this fixed.   


The basic problem is that the longfloat type is not very 
cross-platform.   The functionality depends on your C-compiler / 
platform when a long double is specified as the type.   I suspect it 
doesn't work well with all compilers.  In particular gcc 3.3 on apple I 
know has trouble with the long double type.

Bascially, the "failure" is a failure of the platform.  The best we can 
do in NumPy is not run the test or print something instead of raising an 
error.

Please show us what N.array([1000],dtype=N.longfloat).itemsize is?
