[snip additional Mathieu function test failures]

Hi Giulio,

It looks like I set the computed error tolerances too tight for cases 
where the absolute value of the result is less than 1.  I've attached a 
patch to the specfunc directory that works for me.

The Mathieu functions are new to the trunk, and I've only tested on AMD 
Athlon.  Hopefully a thorough testing on multiple architectures will 
identify any additional issues.

Thanks.
