New Revision: 25282

URL: http://svn.gna.org/viewcvs/relax?rev=25282&view=rev
Log:
Bug fix for the chi-squared gradient calculation in the C module.

The definition of the square() function needed extra brackets so that the 
1/error**2 calculation
would be 1/(error*error) rather than the incorrect 1/error*error form.
