[mesa-users] Compiling Error

[Bill Paxton]

Hi,

The "ndiff" that we use only checks relative errors with no
way to filter out cases where the absolute error is tiny.
This is such a case.  Until someone modifies ndiff,
we have to change our test cases to avoid these false alarms.
This line in the check will need to go.  We'll just change the terminal
output so that it doesn't include this line.  The "floating point fuzz"
that has give the error is clearly insignificant.
