i586: Failure of fit_fix test

[badshah400]

Hi,
Many thanks for your library, which I have benefited from in my work. I also package your library for openSUSE, where it is available from the default repository.

However, it seems that on 32-bit machines the test fix_fit, a part of make check, is failing; while it is perfectly fine on 64-bit machines. Here is a snippet from the log file:

Any help to fix this would be welcome.

I'll increase the tolerance here to fix this later today. Let me know if you have any other problems.
